The Simpson CS20-R 20-Gauge Galvanized Coiled Strap by Simpson is a continuous utility strap engineered to resist tension and uplift loads across a wide range of structural applications. Designed to be cut to length directly on the job site, this coiled strapping solution offers genuine flexibility for single 2x stud or post installations, making it equally at home resisting uplift in floor-to-floor assemblies or managing tension in horizontal applications. Its G90 zinc galvanized coating delivers reliable corrosion resistance, while the lightweight packaging keeps jobsite handling straightforward from start to finish.

Key Features

• Resists roof uplift and shear wall overturning - tackles two of the most critical structural load demands in one versatile strap, reducing the need for multiple specialized connectors
• Cut-to-length design - eliminates waste and guesswork by letting installers size the strap on the job site rather than working around fixed pre-cut lengths
• Cost-effective alternative to pre-cut straps - a single 25 ft. coil covers multiple connections at a lower per-foot cost, helping stretch the project budget without sacrificing performance
• Sized to fit nominal 2x lumber - designed specifically for single 2x stud or post applications so the strap seats correctly without modification or shimming
• 20-gauge steel construction - provides the structural strength needed for tension and uplift resistance while keeping the strap lightweight and easy to work with
• Zinc Galvanized, G90 coating - adds an extra layer of corrosion protection that helps the strap hold up in demanding structural environments over the long term
• Packaged in lightweight cartons - simplifies transport and storage on the job site, reducing handling fatigue when moving materials between work areas

Why This Product

• One coil, many connections - at 25 ft. per coil, this strap gives contractors enough material to handle multiple uplift or tension connections from a single piece of stock, cutting down on trips back to the supply room mid-job
• Built-in job site adaptability - because the strap is coiled and cut to length on demand, it adapts to varying stud heights, post runs, and framing layouts without requiring a separate strap size for every condition
• Corrosion resistance where it counts - the G90 zinc galvanized finish is not just a surface treatment; it is a recognized standard of protection that helps the strap maintain structural integrity in environments where moisture and the elements are a real concern
• Straightforward installation with common fasteners - compatible with 8d or 10d common nails, meaning no specialty hardware is needed, and the installation process fits naturally into standard framing workflows
