The S-5-N 1.5 clamp was designed for application on popular 1.5" nail strip metal roof profiles. An angled wall with a nose permits the S-5-N 1.5 to engage the triangle-type profi les during the installation process, and a wider throat accommodates most nail strip profiles. The combination of these two features allows the S-5-N 1.5 clamp to sit straighter on the seam.

For maximum holding strength, setscrews should be tensioned and re-tensioned as the seam material compresses. Clamp setscrew tension should be verified using a calibrated torque wrench between 160 and 180 inch-pounds when used on a 22-gauge steel, and between 130 and 150 inch-pounds for all other metals, 26ga and thinner gauges of steel. Published data regarding holding strength is available
