CMSTC provides nail slots for easy installation; it can be cut to length. CS are continuous utility straps which can be cut to length on the jobsite. Packaged in lightweight (about 40 lb.) cartons.
- Gauge stamped on part for easy identification
- Galvanized. Some products available in ZMAX® coating. See Corrosion Information.
- Use all specified fasteners; see General Notes.
- Wood shrinkage after strap installation across horizontal wood members may cause strap to buckle outward.
- Refer to the applicable code for minimum nail penetration and minimum wood edge and end distances.
- The table shows the maximum allowable loads and the nails required to obtain them. Fewer nails may be used; reduce the allowable load as shown in the table notes.
- The cut length of the strap shall be equal to twice the "End Length" noted in the table plus the clear span dimension.
- CMST only – Use every other round hole if the wood tends to split. Use round and triangle holes for comparable MST loads, providing wood does not tend to split.
- For lap slice and alternate nailing information, refer to technical bulletin Coil Strap Alternative Nailing Schedule and Lap Splice Specifications (T-CMST).
- CS straps are available in 25' lengths; order CS14-R, CS16-R, CS18-R, CS20-R or CS22-R.

These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.
- Fastener quantities and end lengths are calculated using an increase for wind or seismic loading.
- Use half of the required nails in each member being connected to achieve the listed loads.
- Calculate the connector value for a reduced number of nails as follows:
Example: CMSTC16 in DF/SP with 40 nails total. (Half of the nails in each member being connected)
- Tension loads apply for uplift when installed vertically.
- NAILS: 16d = 0.162" dia. x 3 1/2" long, 16d Sinker = 0.148" dia. x 3 1/4" long, 10d = 0.148" dia. x 3" long. See other nail sizes and information.
