Product Details
The CS is a continuous utility strap designed to resist tension and uplift loads. This coiled strap can be cut to length on the job site and used in a single 2x stud or post application. The CS is ideal for many applications including resisting uplift in a floor-to-floor application and also resisting tension in a horizontal application.
Key Features
- Available in shorter rolls for smaller projects
- Used for roof uplift and shear wall overturning resistance
- A cost-effective alternative to pre-cut straps
Material
- See table
Finish
- Galvanized (G90); ZMAX®
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 attain them. Fewer nails may be used; reduce the allowable load as shown in the Straps and Ties General Notes.
- For lap splice and alternative nailing information, see tables below.
- The cut length of the strap shall be equal to twice the “End Length” noted in the table plus the clear span dimension.
- Lap Splicing
- Lap splicing of coiled straps can be used to extend standard strap lengths for designing continuous drag elements and diaphragm chord members. The Strap Lap Splices table provides the minimum splice length (Lsp) and fasteners, within the splice length, to achieve the highest allowable capacity of the strap.
- The Allowable Loads for Alternative Nailing table provides information for coiled straps when installed with different nailing schedules. The highest allowable load given for each model is limited by the steel capacity.
- The Engineer/Designer of Record must evaluate and determine the adequacy of the coiled strap’s lap splice and alternative nailing applications to meet their design loads.
Options
- CS straps are available in 25' lengths; order CS14-R, CS16-R or CS20-R
- For stainless steel, order CS16SS-R

- See Straps and Ties General Notes.
- Calculate the connector value for a reduced number of nails as follows:
Example: CS16 in DF/SP with (18) 0.148 x 2 1/2" nails:
(Half of the nails in each member being connected)
- See table below for alternate nailing and lap splice information.
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
Strap Lap Splices
- See Straps and Ties General Notes.
- 0.148" x 2 1/2" nails can be replaced by 0.148" x 3 1/4" nails. No other nail substitution is allowed for lap splices.
- Refer to the applicable code for minimum edge distance and minimum end distance.
- No strap modification is allowed and the splice must meet both the minimum number of fasteners and the minimum splice length.
Allowable Loads for Alternative Nailing
- See Straps and Ties General Notes.
- Fasteners: Nail dimensions in the table are listed diameter x length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
