The Simpson Strong-Tie CS20 Coiled Strap is a continuous galvanized framing strap for wood-to-wood fastening and structural tie applications. This is a coiled utility strap designed for tension and uplift resistance. Model Number: CS20. If you need a long roll you can cut on site for custom lengths, this is the kind of hardware that makes more sense than stocking a pile of pre-cut straps.

For the CS20 size, you get a 250 ft. roll made from 20-gauge steel with a 1-1/4 in. width sized to fit nominal 2x lumber. In real terms, that means you can run the strap exactly where the framing layout demands and trim it to suit the span, repair, or reinforcement point instead of forcing a standard strap into a non-standard job.

Simpson positions the CS series for resisting tension and uplift loads, including roof uplift and shear wall overturning resistance. That matters on framing jobs where load path continuity is the whole point. A continuous strap gives you flexibility for field-cut lengths while still using a purpose-built connector from a brand contractors already trust for structural hardware.

The G90 galvanized finish is there for corrosion resistance in the environments this type of connector typically sees in general framing and structural reinforcement work. It is not just about shelf life. Galvanizing helps the strap hold up over time in standard jobsite and building conditions where bare steel would be the wrong call.

Another practical advantage is efficiency. Simpson specifically calls the CS straps a cost-effective alternative to pre-cut straps, and that is easy to understand once you are working through multiple tie locations with different required lengths. One roll can cover a lot of layout conditions, especially on smaller projects, punch-list repairs, or custom reinforcement work where exact length changes from spot to spot.

Installation details matter with this kind of product. Simpson notes that you should use all specified fasteners and follow applicable code requirements for minimum edge and end distances. Lowe's also identifies installation with 10d or 8d common nails for this model. The basic takeaway is simple: the strap itself gives you flexibility, but the final performance still depends on using the correct fasteners and following the published fastening pattern for the application.

This coiled strap is a strong fit for framers, remodelers, general contractors, and serious DIY users handling structural repairs, uplift reinforcement, or custom wood framing connections. If you want a fixed-length connector, buy a fixed-length strap. If you want one roll that can handle a wide range of tie lengths on the job, the CS20 is the more useful option.

Simpson Strong-Tie CS20 Coiled Strap is the smart buy when fixed lengths slow you down

This is the strap you buy when you want one roll on the truck that can cover a pile of custom tie-down and reinforcement details without wasting time hunting for the perfect pre-cut length.

• Who it's for: Framers, remodelers, and contractors doing wood framing reinforcement, uplift tie work, and structural repairs.
• Why it stands out: The 250 ft. roll, 1-1/4 in. width, and cut-to-length format make it more versatile than fixed straps for field work.
• Worth knowing: This is connector hardware, not generic flat metal. Use the correct fasteners and follow the published fastening pattern and code requirements if you expect the load path to mean anything.
