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.

• No routing required; the strap can be placed directly on top of mass timber panels, reducing manufacturing time and cost
• Less susceptible to moisture damage than plywood splines, reducing need for expensive repairs
• Embossed hole helps guide the installation tool into the hold and increases capacity per fastener
• Tested for in-plane shear values
• Can be used as part of a complete spline solution throughout a project for faster installation and to save on the total cost of spline connections

Use all specified fasteners.
