MDSS Medium Diaphragm Spline Strap
On This Page
The MDSS96 surface spline is 95 1/2" long, is attached with Strong-Drive® SDS Heavy-Duty Connector screws and is an ideal solution for CLT diaphragms. For CLT manufacturers, it reduces costs by eliminating or reducing time for milling at panel edges. And since our tabulated values are based on tests, not just calculations, Designers can value-engineer a solution using fewer screws than calculated solutions would allow.
- Pre-punched screw holes speed fastener installation
- Tested loads allow for value-engineered solutions using fewer screws than calculated solutions would allow
- Reduces or eliminates the need for edge-milling of CLT panels
- 14 ga.
- Galvanized (G90)
- Use all specified fasteners/anchors
