The Simpson CS18-R 18-gauge galvanized coiled strap is a continuous utility strap built to join and reinforce structural connections across a wide range of light-duty and heavy-duty framing applications. Sized to fit nominal 2x lumber, it installs on either the wide or narrow face of a member, giving framers and contractors the flexibility to handle diverse connection configurations without modification. Because it ships as a 25 ft. coil that can be cut to any required length on the job site, a single roll covers multiple connections and adapts to job-specific requirements without generating unnecessary material waste. The G90 zinc galvanized coating delivers extra corrosion resistance, making this coiled strap a dependable choice wherever moisture exposure is a factor.

Key Features

• Sized to fit nominal 2x lumber - installs on the wide or narrow face of a member, adapting to a variety of framing and joint reinforcement scenarios without modification.
• 25 ft. continuous coil, cut to length on site - eliminates the need to stock multiple pre-cut strap sizes and reduces material waste on the job.
• 18-gauge steel construction - provides the structural strength needed for both light repairs and heavy-duty tension and joint reinforcement applications.
• G90 zinc galvanized coating - delivers extra corrosion resistance for use in moisture-prone environments where long-term durability matters.
• Install with 8d or 10d common nails - works with widely available fasteners that most framing crews already carry, keeping installation straightforward.
• Packaged in a lightweight carton - easy to transport and handle on the job site, reducing fatigue during setup and staging.

Why This Product

• One coil, countless cuts - the 25 ft. continuous format means a single roll can be trimmed to whatever length each connection requires, giving framers and repair crews precise control over material use without waste.
• Built for flexibility across applications - compatible with both the wide and narrow face of nominal 2x lumber and suitable for everything from quick residential repairs to demanding structural framing projects, reducing the need for multiple connector SKUs on a single job.
• Corrosion resistance where it counts - the G90 zinc galvanized finish goes beyond basic protection, making this strap a reliable choice for framing connections exposed to humidity, weather, or other moisture-related conditions over time.
• Straightforward installation with common fasteners - compatibility with 8d or 10d common nails means no specialty hardware is required, keeping installation efficient and material costs predictable.
