Product Details
The CMST is a continuous utility strap designed to resist tension and uplift loads. This coiled strap can be cut to length on the jobsite and used in a double 2x stud or post application. The CMST is ideal for many applications including resisting uplift in a floor-to-floor application and also resisting tension in a horizontal application.
Key Features
- Used for roof uplift and shearwall overturning resistance
- A cost-effective alternative to precut straps
Material
- See table
Finish
- Galvanized (G90)
Installation
- Use all specified fasteners; see General Notes.
- Refer to the applicable code for minimum edge and end distances.
- The table shows the maximum allowable loads and the screws required to obtain them. See footnotes. Fewer screws may be used; reduce the allowable load by the code lateral load for each fastener subtracted from each end.

Load Tables
- Use half of the fasteners in each member being connected to achieve the listed loads.
- For CMST straps: End Length (inches) = 1/2 total fasteners x 7/8" + 1" when all holes filled. Double length if only round holes filled.
- For CMSTC16 straps: End Length (inches) = 1/2 total fasteners x 3/4" + 1" when all holes filled. Double length if only round holes filled.
- Total Cut Length = End Length + Clear Span + End Length.
- Calculate the connector value for a reduced number of screws as follows: Allowable Load =
Example: CMSTC16 on 54 mil with 24 screws:
- Loads are based on lesser of steel strap capacity and AISI S100 fastener calculation.
