The Heavy Limb Treehouse Attachment Bolt (HL TAB) is the bigger, badder version of a Standard Limb TAB. The HL TAB has a 1 3/4" 4140 heat treated steel shank with a mild steel 3" diameter boss hydraulically pressed on to fit. It may eclipse the load capacity of a standard TAB by up to three times.* We use the HL TAB in tandem with custom hardware and our HL versions of the DUA and SUA brackets. It can also be used with a HL suspension system. This massively strong TAB requires an HL Pilot Bit Combo and a 1 3/8" x 18" auger bit, so make sure to order the appropriate accessories. This is serious hardware for a serious treehouse project. As with all our hardware, when installed and used correctly, HL TABs are quite tree-friendly. 24.55 lbs Learn about the testing we have done with our TABs. *Please note that our TABs do not have weight ratings. The weight TABs are able to bear will greatly depend on the species and health of the tree, as well as many other factors. We highly recommend consulting with one of our team members, a professional arborist and/or engineer before starting your project.
