The Simpson CMST12 Coiled Strap Tie 12-Ga Galvanized G90 40 ft Cut-to-Length Medium Strap from Simpson is a continuous coiled medium strap engineered to join and reinforce structural connections across a wide range of applications - from light-duty repairs to heavy-duty projects. Packaged as a 40 ft. coil, this strap is designed to be cut to length directly on the job site, giving installers full control over piece sizing for each unique connection. Built from 12-gauge steel and finished with a G90 galvanized coating for extra corrosion resistance, the CMST12 delivers a versatile, reliable solution for contractors and builders tackling wood-to-wood connections on the wide or narrow face of lumber. It can also be applied back-to-back on a piece of lumber without fastener interference, making it a practical choice for double stud and post assemblies alike.

Key Features

• Nail slots for easy installation - pre-formed slots guide fastener placement and speed up the installation process, reducing layout time on the job site.
• Cut-to-length design - the 40 ft. coil lets you size each piece exactly as needed on site, eliminating waste and allowing the strap to fit a wide variety of connection lengths in a single roll.
• Staggered nail pattern - offsets fastener rows to maximize holding strength and allow back-to-back installation on a single piece of lumber without fastener interference.
• 12-gauge steel construction - provides the structural rigidity and load capacity needed for both light repairs and heavy-duty framing connections.
• G90 galvanized coating - the zinc galvanized finish delivers extra corrosion resistance, extending the service life of the strap in moisture-prone environments.
• Compatible with common nails - installs with standard 10d or 16d common nails, so no specialty fasteners are required and the connection remains straightforward for any crew.

Why This Product

• One roll, countless applications - because the CMST12 is designed to be cut to length on the job site, a single 40 ft. coil covers multiple connection points in one purchase, making it a cost-effective choice for framing crews handling varied strap lengths throughout a project.
• Versatile enough for wide or narrow face lumber - the strap can be applied to either face of dimensional lumber and used back-to-back without fastener interference, giving builders flexibility across double stud assemblies, post connections, and other configurations without switching products.
• Built for corrosion-prone environments - the G90 zinc galvanized finish provides extra corrosion resistance, making the CMST12 a dependable choice in applications where long-term moisture exposure is a real concern.
• Simplified installation with familiar fasteners - nail slots, a staggered nail pattern, and compatibility with common 10d or 16d nails mean faster, more consistent installations without specialized tools or hardware.
