The Simpson CMSTC16 Coiled Strap Tie from Simpson is a 54-foot, 16-gauge steel coiled strap designed to join and reinforce framing joints across a wide range of structural connections. Packaged as a coil and built to be cut to length directly on the job site, it gives contractors and builders the flexibility to tackle everything from light repairs to heavy-duty framing work. The strap can be installed on either the wide or narrow face of lumber, and its pre-punched nail slots with a staggered nail pattern make fastener placement straightforward with 16d sinkers. A G90 zinc galvanized finish delivers added corrosion resistance, making this coiled strap tie a dependable choice wherever reliable tension reinforcement is needed.

Key Features

• Cut-to-length coil format - the 54-foot coil is specifically designed and packaged to be cut to any required length on the job site, so you use only what each connection demands and reduce material waste.
• Pre-punched nail slots - eliminate the need to mark or drill fastener locations, speeding up installation and keeping the work consistent from one connection to the next.
• Staggered nail pattern - spaces fasteners to help prevent wood splitting and allows back-to-back strap placement on a single piece of lumber without fastener interference.
• 16-gauge steel construction - provides the structural strength needed for both light repair work and heavy-duty framing connections across a variety of lumber dimensions.
• G90 zinc galvanized finish - offers a higher level of corrosion resistance suited to demanding construction environments where long-term performance matters.
• Wide or narrow face installation - the versatile profile works on either face of dimensional lumber, giving you more placement options without requiring a different strap for each situation.

Why This Product

• One coil, unlimited cut lengths - instead of stocking multiple pre-cut strap sizes, a single 54-foot coil covers custom lengths across a full day of varied framing and repair tasks, reducing trips to restock material.
• Simplified fastening from the start - pre-punched nail slots paired with a staggered pattern mean less layout time and a cleaner, more consistent nail line whether you are reinforcing a single joint or working through a large framing project.
• Built for lasting structural performance - the combination of 16-gauge steel strength and G90 galvanized protection means the strap holds up under load and resists corrosion over time, even in challenging jobsite conditions.
• Flexible enough for the full range of connections - suitable for placement on the wide or narrow face of lumber and applicable to light repairs as well as heavy-duty structural work, this coiled strap tie adapts to the connection rather than limiting it.
