Frequently Asked Questions

What is the Simpson Strong-Tie E20/3 angle bracket used for?

The E20/3 angle bracket is used to connect cross-laminated timber (CLT) wall panels to concrete slabs. It is part of Simpson Strong-Tie's E series of angle brackets designed specifically for CLT construction applications.

What is the maximum base-of-wall gap this bracket is rated for?

The E20/3 angle bracket has been load-rated with up to a 2-inch gap between the bottom of the CLT wall and the top of the concrete slab. This allows the wall to be separated with a pressure-treated sill plate, concrete curb, grout pad, or other specified material.

What fasteners are recommended for installing the E20/3 bracket?

The E20/3 can be installed with (18) #10 x 2-1/2 in. Strong-Drive SD Connector screws and (2) 3/8 in. anchor bolts; or (18) 0.162 in. x 2-1/2 in. nails and (2) 3/8 in. anchor bolts; or (3) SDHR27400 0.275 in. x 4 in. Strong-Drive SDHR Combo-Head screws and (2) 3/8 in. anchor bolts.

What material and finish is the E20/3 angle bracket made from?

The E20/3 is made from 11-gauge steel with a Zinc Galvanized, G90 finish, which provides extra corrosion resistance and heavy-duty load capacity suitable for structural CLT-to-concrete connections.
