Product Overview
LDSS48 Light Diaphragm Spline Strap
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.
Key Features
- 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
Material
- 18 gauge
Finish

Installation
- Place the strap on the surface of the panels with the centerline notches aligned with joint between adjacent panels.
- From a standing position, hold tool perpendicular to the face of the strap and place the noseclip over the embossed feature. Drive the screw. Repeat.

Options
- The LDSS has also been tested with 0.148" x 2 1/2" nails for specifiers or contractors who prefer a nailed connection. The embossed hole allows for the use of a power framing nailer using concentric, full round-head nails.
