Key Features

• Gauge stamped on part for easy identification

Finish

• Galvanized. Some products available in ZMAX^® coating. See Corrosion Information.

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 table footnote #1. Fewer screws may be used; reduce the allowable load by the code lateral load for each fastener subtracted from each end.

Options

• CS straps are available in 25' lengths; order CS14-R, CS16-R, CS18-R, CS20-R or CS22-R.

CS/CMST Coiled Strap — Tension Tie Application

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

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. For CS straps: End Length (inches) = 1/2 total fasteners + 1".
5. Total Cut Length = End Length + Clear Span + End Length.
6. Calculate the connector value for a reduced number of screws as follows:

   

   Example: CMSTC16 on 54 mil with 24 screws

   

7. Loads are based on lesser of steel strap capacity and AISI S100 fastener calculation.
8. See more on Simpson Strong-Tie fasteners.

CS Coiled Strap — Stud Bridging Application

1. In order to achieve the tabulated loads in the strap, attach each strap to the blocking with the tabulated number of screws.
2. Strap length at blocking to achieve tabulated load = number of tabulated screws + 1".
3. Calculate the strap value for a reduced number of screws to the blocking as follows:

   

4. See more information on Simpson Strong-Tie fasteners.
