The S-5-N 1.5 clamp boasts an angular throat that accommodates most nail strip profiles, minimizing the need to field crimp. An angled wall with a nose permits the S-5-N 1.5 to engage the triangle type profiles during the installation process—there is no longer a need to hold the clamp in place while setscrews are tensioned. The combination of these two features allows the clamp to sit straighter on the seam.
