This product's information may differ depending on the category of use. You are currently viewing details related to Lateral Connectors, Ties and Straps. You can also view product information related to the category: Coiled Straps

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

  1. Use half of the fasteners in each member being connected to achieve the listed loads.
  2. 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.
  3. 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.
  4. Total Cut Length = End Length + Clear Span + End Length.
  5. Calculate the connector value for a reduced number of screws as follows: Allowable Load =

    Example: CMSTC16 on 54 mil with 24 screws:

  6. Loads are based on lesser of steel strap capacity and AISI S100 fastener calculation.
  7. See Fastening Systems for more information on Simpson Strong-Tie fasteners.
