TBE Truss Bearing Enhancers

The TBE transfers load from the truss or girder to plates for bearing-limited conditions, and provides exceptional uplift capacity. Replaces nail-on scabs that provide lower load transfer, or in some cases, an additional ply when needed for bearing. One size works with any number of girder plys.

The table lists allowable loads for TBE4 used on 2x4 and TBE6 used on 2x6 top plates. The table gives the different loads calculated for TBE with and without wood bearing. See Fastener Schedule and Alternate Installation below.

Material: 18 gauge.

Finish: Galvanized. See Corrosion Information.

Installation:

Use all specified fasteners. See General Notes.
TBE must be installed in pairs.
Top plate size is 2x4 for TBE4, 2x6 for TBE6. Use alternate installation for TBE4 and TBE6 on larger plates or pre-sheathed walls. See Alternate Installation.

Two TBE installed with single-ply truss

Alternate Installation:


Pre-sheathed shearwall. Bend tab along slot and nail one leg to top of the plate.		TBE6 Installed on Double 2x8 Top Plate

Alternate Installation Allowable Down Loads are 0.80 and Allowable Uplift Loads are 1.0 of the TBE only table loads, below.

Loads are for a pair of TBEs.
When truss chord wood species is different than the wall top plate wood species, choose the tabulated allowable loads based on the species with the lower tabulated download capacity.
Allowable loads have been increased 60% for wind or earthquake loads with no further increase allowed. Reduce where other loads govern.
Allowable loads are determined only by nail shear calculations or tests of the metal connectors based on the lowest of 0.125" of deflection or the ultimate load with a 3 times factor of safety. The attached wood members must be designed to withstand the loads imposed by the nails.
Perpendicular to Plate loads are reduced for Alternate Installation.
Parallel to Plate loads are not reduced for Alternate Installation.
Equivalent Top Plate Bearing Width is the actual top plate width (TBE4 = 3 1/2", TBE6 = 5 1/2") plus the enhanced bearing width provided by the TBE.
