S-5-NH 1.5

The S-5! NH 1.5 Clamp is engineered to fit 1.5″ (38 mm) nail-strip roof profiles with wider horizontal base dimensions. Its hinge insert design adapts to both wide and medium width profiles without damaging seam material. Angled Torx-T30 setscrews, a reversible toe insert, and a staked hinge make installation easier and more reliable. The standard version includes two setscrews and an M8 bolt for accessory mounting; a Mini version provides similar benefits for lighter loads. The clamp is tested for heavy-duty applications such as snow retention, solar modules, and utility attachments.

Key Features:

• Fits 1.5″ (38 mm) nail-strip profiles with base dimension > 0.475″ and ≤ 0.800″
• Reversible hinge insert that conforms to panel seam shape and includes a toe to engage the female portion of the profile
• Angled Torx-T30 round-point setscrews for easier tool access during installation
• Standard clamp includes two setscrews plus an M8 bolt; Mini version uses one setscrew, no bolt (for lighter loads)
• Hinge insert is staked at one end for stability; designed to reduce seam deformation

• Seam height: 1.5″ (38 mm) nail-strip profile
• Horizontal base dimension: > 0.475″ and ≤ 0.800″ (≈ 12 mm to 20.3 mm)
• Setscrews: Two 3/8-24 × 0.80″ Torx-T30 round-point (standard); Mini version has one setscrew
• Bolt: One M8-1.25 × 16 mm bolt included (standard version)
• Material: Structural aluminum clamp body; stainless steel hardware (setscrews and bolt)
• Includes: Clamp body, hinge insert, setscrews, M8 bolt, Torx drive bit tip

• Select roof seam profile that is 1.5″ (38 mm) nail-strip and has a base flange horizontal dimension > 0.475″ up to 0.800″.
• Insert the hinge insert (toed portion facing female seam) into the clamp body; ensure hinge is staked at one end.
• Position clamp over seam; ensure toe of hinge engages female portion of the panel.
• Insert and hand-tighten the Torx-T30 setscrews (two for standard, one for Mini) to seat the clamp body.
• For standard version, insert M8 bolt for accessory mounting. Tighten all hardware to manufacturer’s torque specifications.
• After initial load (e.g., snow or wind) and seasonal expansion/compression, re-check setscrew torque and alignment.

Q: What roof profiles is the NH 1.5 clamp designed for?
A: It is for 1.5″ (38 mm) nail-strip panels with wider base dimensions (>0.475″ and ≤0.800″), such as VicWest Prestige, NewTech FF150, and similar profiles.

Q: What does the reversible hinge insert do?
A: It allows the insert to conform to both medium-width and wider nail-strip profiles, engaging the female seam portion and reducing damage or seam distortion.

Q: What is the difference between the standard and Mini version?
A: Standard version uses two setscrews and includes an M8 bolt; Mini version uses one setscrew and does not include the bolt—it’s meant for lighter loads.

Q: Is this clamp suitable for snow retention systems?
A: Yes. The standard NH 1.5 clamp is intended for heavy-duty situations such as snow retention, solar, and utility attachments, pending correct seam profile and base dimensions.
