Heavy Duty 3x4 Treehouse Attachment Bolt (TAB) - Powder Coated - Treehouse Supplies

3x4 Heavy-Duty Treehouse TAB - Powder Coated

With the ever increasing demand for larger and more commercialized tree platforms and treehouses, the need for stronger single-point, artificial limbs arose. Our Heavy-Duty Hardware Line was introduced to meet these requirements and fulfill the engineering limitations of our Standard TABs.

Heavy-Duty Treehouse Attachment Bolts are an augmented and re-engineered adaptation of our original design that still uses the 3" collar, but with a 1¾" diameter shaft vs the traditional 1¼", increasing the amount of leverage that can be applied.

Like our original bolts, Heavy-Duty TABs would be incomplete without a wide variety of accompanying and compatible brackets, fitted to support treehouse of all sizes, shapes and heights in a multitude of ways. All our bolts and brackets are designed to allow the trees movement and growth, keeping your outdoor investment secure and the trees healthy.

Our professionally powder coated TABs offer an additional layer of protection against the elements, providing more longevity and prolonging your project.

Please note:

For Treehouse Attachment Bolt installation, we recommend using our:
- Drill Bit Rental Kit for boring the hole the TAB will sit in.
- TAB Ratchet for turning in the TAB w/o damaging the exterior.
- Water Level Tube if 2 or more TABs are to be installed.
Only 1¾" brackets will work with HD-TABs.
We do not recommend using the HD-TAB 3x4 with our floating bracket. It is too short to allow for proper movement.

What are TABs? Which parts does it include? How’s the installation process?

TABs are an adaptation of timber bolts with built-in sheer collars. Since the late 1990s, the ideas have been applied to treehouse construction.

Our TABs, in their current form, are the best-performing treehouse bolts in the industry based on side-by-side testing.

Our TABs are the strongest TAB on the market.

For an introduction to the parts of the TABs, see our TABs 101 video here: https://www.youtube.com/watch?v=iRDiUgL8S3s&themeRefresh=1

Which TAB size do I need?

The best TAB size is a factor of the design loading on the tree attachment point, the species of tree you are building in, and the safety factor for your design.

Design loading is something that engineers figure out to determine how strong to design a structure – it is based on building codes, whether commercial or residential and geography (zones for high wind or snow).
Tree species can vary in North America by approximately a 5:1 ratio, with the hardest trees, like live oak or some of the hickories outperforming ponderosa pine or eastern white pine by 4x to 5x. In most cases, our TABs do not fail, but the wood of the tree can crush beneath the TAB, causing it to tilt down when overloaded. A larger TAB will support more before the wood crushes.
Safety Factor: If you think the max load at a given point will be 3000 pounds, then you may decide to get a TAB that will support 6000 or 9000, and that would give you a 2:1 or 3:1 safety factor, respectively.

If you prefer to have “extra support” so that you cover your anticipated loads with a safety factor, then upgrade the hardware to play it safe.

We have various options for consultations to review your intended plans, evaluate your tree species, and make hardware recommendations. You’ll get advice on hardware and learn more about construction. We have decades of experience with over 1000 treehouses.
If cost is no object, larger TABs are better. Our affiliated construction company, Tree Top Builders (www.treetopbuilders.net), seldom uses 1” collars for construction, except in rare situations. The 3x9 and 6x12 TABs are their standard.

How much do TABs hold?

The smallest TABs with 1” collars, such as our 1x6 or 1x9 TABs, have been tested at 2,000 – 12,000 pounds each, based on the type of tree.

Some of our systems built with larger TABs hold over 30,000 lbs. However, there are some disclaimers:

Do not make the mistake of assuming that all TABs in a treehouse are supporting an equal amount of load.
Do not forget to account for dead load, live load, and other loads such as snow, wind, etc.
Do not assume that a TAB from another company will support our exact amounts. Our TABs in side-by-side testing supported 60% more than some of our competition, producing look-alike products by taking shortcuts in the manufacturing process to save a few bucks.

My treehouse has grown, and it needs new tabs. What can I do?

If possible, we prefer to work with the existing hardware because it’s better for the tree and usually saves you money and time too!

We make extension brackets that can get you more years of use from the same TAB.

These solutions are custom. So if you have any doubts, please feel free to contact us here!

What is the smallest size tree I can attach tabs to?

The smallest size tree you can attach tabs to would depend on the tab used and the tree itself.

However, typically, the smallest tree we have seen being used is a 10" tree.

Why do we need two static and two dynamic arrestors when using TABs? Why not only dynamic arrestors?

We understand you might be wondering about using static and dynamic arrestors when using TABs.

While we don't currently have plans for two static and two floating arrestors, we can provide some general information.

In most cases, when there are multiple trees, one is static, and the rest are floating. If there are any posts, all tree connections are floating (dynamic).

Can TABs be removed once installed?

TABs and other treehouse bolts can be removed, but there is a potential risk of causing additional damage to the tree during the process.

The level of risk is relatively low if the bolts were recently installed. However, if the tree has grown around the TAB collars, removing the bolts may require some tree tissue removal, increasing the risk.

Considering the potential for damage upon removal and the extra damage caused by reinstalling the bolts in a different location on the tree, we generally explore alternative options before attempting to reuse the bolts.

These alternatives could involve modifying the brackets, using different lumber sizes, adding spacers, or making other small design changes depending on the specific situation. If possible, it's always best to use the bolt in its original location.

When it comes to removing the bolt, you may be able to turn it out backwards using the same wrench you used to install it. However, with TABs, it is usually not possible to back them out using the nut on the end, so you will likely need a large pipe wrench and turn it out by the perch/shaft. To protect the powder coating and minimize stress on the metal, we recommend wrapping the tab in thick rubber inside the jaws of the pipe wrench. You may also need to use a pipe on the back of the pipe wrench handle to gain enough leverage for removing a TAB.

If removed properly, our TABs can be reused to support a treehouse. However, be cautious not to install the bolt too close to the original hole, as this may cause the two wounds in the tree to join together. While the recommended distance may vary, a conservative rule of thumb is to have 24 inches of vertical separation and 6 inches of horizontal separation.

We Ship Worldwide!
International orders, Duties and Taxes:

International orders may be subject to Duties and Taxes by the receiving country. These Duties and Taxes are the sole responsibility of the recipient. Since the amount varies depending on the country, TreeHouse Supplies, Inc. is not able to estimate the amount prior to shipping the order. If you have questions about Duties and Taxes, you should contact the appropriate government office in your receiving country and determine the amount you will be required to pay. If you refuse to pay the duties and taxes, the shipping company will deny delivery of your order and return it to TreeHouse Supplies, Inc. If this happens we will deduct the cost of the return shipment from your refund amount. If we receive a bill for duties and taxes unpaid by you the customer, we will invoice you for those fees and you are obligated to pay.

We will not ship to freight forwarding companies. We use Fedex to deliver all of our worldwide shipments.

Window Shipping:

FedEx charges by DIM weight not actual window weight. You can click here to see how they calculate the shipment. So for example: Our 24x36 window's actual weight is 20 lbs, however, FedEx will rate the package at 57 lbs. because the box size is 38" x 8" x 26". Please email us if you have any questions prior to ordering.

Express Order Restrictions:
Express orders must be received by 2pm EST to be guaranteed to ship that day. Express orders received after that time will be sent out the following day.

We may charge a fee if the shipment has to be hand delivered to the commercial shipper. The fee is based on a case by case basis. Some products that require customization or special orders are not available for immediate shipping - i.e. Bridge Kits, Rustic Swings. If you are unsure, contact us for clarification.

We want you to be able to buy with confidence, so we accept returns for any reason according to this policy.

There is a 15% restocking fee for returned kits that are not being exchanged and are not damaged. Kits returned to us AFTER 14 days and WITHOUT contacting us, will NOT be refunded.

Customer is responsible for all return shipping costs.

Spider Swings Policy:

Due to the size of the spider swings, they are very expensive to ship. Some of the FedEx oversize charges can be in excess of $80.00 and that is on top of the regular shipping fees. If you wish to return a spider swing, you are responsible for the cost to ship the swing back. The amount you will be refunded will also have the initial cost of shipping the swing to you deducted from it since FedEx will not refund that money to us. We also will deduct a 15% restocking fee. When you total up the cost to ship the swing back to us and the reduced refund, it may better to keep it. Please read and understand this policy prior to buying your spider swing. There are no exceptions to this policy unless the swing has a proven manufacturing defect. Contact us with any questions prior to ordering a swing or sending a spider swing back.

Return for Credit: If you accidentally ordered the wrong parts, want something different from our store instead, or have missed the 21 day refund cutoff date, then we may, at our sole discretion, issue store credit for your return. However, after 3 months from your order date, no refunds or store credit will be issued for any reason. Please contact us prior to sending any items back to confirm if you are eligible for either a refund or store credit. We will then issue you a return merchandise authorization (RMA) number to send your items to us. Items returned to us without an RMA number will not be accepted. Customer is responsible for all return shipping costs.

Restocking Fees / Shipping Costs

You may not get a full refund if we are not at fault. We may withhold shipping costs and/or apply a restocking fee.

We hold shipping costs because we ship most items for free. When accepting returns where we are not at fault, we will withhold actual shipping costs that we paid to ship your order to you originally.

Restocking Fees are withheld from your return/credit when we are not at fault. The standard fee is 15%. Some products such as zip line parts / kits and windows are 25% due to the sensitive nature of these products. If a powder coated item is returned and it is scratched or chipped, there will be a $15.00 charge per item to re-powder coat it. This will be deducted from your refund.

As an example, if you pay $100 for product and it ships free, then you return it, we will withhold shipping costs, say $17, plus the restocking fee. So approximately $68 would be returned to your credit card. This is what it takes for us to break even on a returned transaction. Customer is responsible for all return shipping costs.

Exclusions:

The following Products are not returnable:

Custom Designs and/or plans
Cut rope or netting is not returnable
"Discount Corner" items are not returnable.
Custom Manufactured parts that will likely never be resold such as cargo, hammock, loft, and barrier nets.
Cable that has been removed from the spool.
Used parts if their use changes their condition to not saleable. Examples: Zipline trolleys used once, TABs turned in with a pipe wrench, etc...
Carabiners and climbing gear that has left our sight in the industry is considered used and can't be returned.

Contact us immediately if you have questions about returning your items.

If you want to request an exception to this policy, please contact us and we will consider each case separately. Whether or not we make an exception, and the terms of any such exception, will be at our sole discretion. But if you get stuck with something you don't want, it doesn't hurt to ask and we may be able to do something for you. We are real people, not robots or a big corporation.
