S-5-N 1.5

The S-5! N 1.5 Clamp is engineered for 1.5″ (38 mm) nail strip metal roof profiles. It combines a wider throat and an angled wall with a nose to engage triangular nail strip ribs securely—minimizing or eliminating the need for field crimping. With dual round-point T-30 Torx setscrews and an M8 top bolt, this non-penetrating clamp is ideal for supporting heavy-duty rooftop attachments like snow guards, solar mounts, and equipment supports while preserving roof warranties.

Key Features:

• Designed for use on 1.5″ (38 mm) nail strip metal roof profiles, including Tru Snap, NailStrip, NS 1.5, SMI 1.5 and similar profiles
• Wider throat design and angled wall with nose to engage profiles and reduce crimping effort
• Non-penetrating clamp that preserves roof panel integrity and coatings
• Two T-30 Torx round-point setscrews and one M8 bolt for strong, reliable attachment
