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.

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.
  • 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).

Options

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

Not Sure How Much Coil Strap You Need?
Simpson Strong-Tie has a web-based app, the Coil Strap Length Calculator, which can help you quickly determine the cut length of each strap and the total amount of coil strap needed for each application on a project.

    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.

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

  1. Fastener quantities and end lengths are calculated using an increase for wind or seismic loading.
  2. Use half of the required nails in each member being connected to achieve the listed loads.
  3. 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)

  4. Tension loads apply for uplift when installed vertically.
  5. 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.
