Simpson Strong-Tie LDSS48 - 48" Light Diaphragm Spline Strap - G90 Galvanized

The LDSS light diaphragm spline strap is designed to be placed directly on top of CLT (cross-laminated timber) and other mass timber panels to connect them together. Unlike plywood splines, the LDSS does not require routing. As part of the Simpson Strong-Tie^® complete LDSS spline solution, the steel strap installs easily and safely using our PRO300SG2 Quik Drive^® tool and collated Strong-Drive^® WSV Subfloor screws. The LDSS features an innovative embossed hole design that helps guide the installation tool and increase fastener capacity.
