LDSS Spline Solution for Mass Timber
A Faster, More Economical Spline Connection Than Plywood
Save labor and manufacturing costs with the LDSS spline solution from Simpson Strong-Tie. Unlike plywood splines that require routing, the LDSS light diaphragm steel spline strap can be placed directly on top of CLT or other mass timber panels. It installs easily and safely with our PRO300SG2 Quik Drive® tool and collated Strong-Drive® WSV Subfloor screws. An innovative embossed hole design helps guide the installation tool and increases fastener capacity. Typical mass timber projects can save on the total cost of their spline connections by switching to the LDSS system, with multiple additional advantages over plywood splines.
