S-5-N 1.5 Mini

The S-5! N 1.5 Mini Clamp is designed for 1.5″ (38 mm) nail strip metal roof profiles where extremely heavy load capacity isn’t required. It is a compact variant of the full N 1.5 clamp, using a single Torx-T30 round-point setscrew instead of two, and omits the M8 bolt to reduce cost and simplify installation. Like the full clamp, it has an angled wall with nose that engages triangular rib profiles, helping the clamp seat properly without needing field crimping. It is suitable for mounting lighter roof accessories such as satellite antennas, conduit, signage, solar micro-mounts, and other service attachments.

Key Features:

• Designed for 1.5″ (38 mm) nail strip profiles requiring lighter-duty attachments
• One Torx-T30 round-point setscrew for non-penetrating, lower cost installation
• Angled wall with nose engages triangular-rib profiles to improve fit and reduce distortion
• Omission of top bolt for simpler, streamlined design in Mini version
• Stainless hardware to resist corrosion; maintains roof warranty

• Seam height: 1.5″ (38 mm) nail strip profiles
• Seam base / rib dimension: ≤ 0.50″ (12.7 mm)
• Number of setscrews: One 3/8-24 × 0.80″ round-point Torx-T30 setscrew
• Material: Structural aluminum clamp body; 300-series stainless steel hardware
• Dimensions (approximate clamp body): throat width ≈ 1.50″; height ≈ 1.50″; depth from seam flange ≈ 2.18″; body length ≈ 2.25″; width ≈ 1.65″
• Includes: Clamp body, one setscrew, Torx bit tip

• Confirm that the roof panel profile is a 1.5″ (38 mm) nail strip roof with seam base ≤ 0.50″.
• Position clamp body over the seam so angled wall with nose aligns with rib geometry.
• Insert the single round-point setscrew and thread by hand to engage seam without overlapping material.
• Tighten the setscrew using a Torx-T30 bit to the manufacturer’s torque specification.
• Mount the accessory using separate bolt if the accessory requires, keeping clamp alignment stable.
• After installation and under load or thermal cycles, re-check the setscrew torque and alignment.

Q: What profiles is the N 1.5 Mini clamp compatible with?
A: It fits metal roof profiles with 1.5″ (38 mm) nail strip seams and a base rib dimension ≤ 0.50″ (12.7 mm).

Q: How does the Mini version differ from the standard N 1.5 clamp?
A: The Mini has one setscrew instead of two and excludes the M8 bolt, making it lighter-duty and more economical.

Q: Is the N 1.5 Mini clamp suitable for snow retention systems?
A: No. Mini clamps are not compatible with full snow retention systems like SnoRail/SnoFence or ColorGard.

Q: What materials are used in this clamp?
A: The clamp body is structural aluminum, and the setscrew hardware and bit tip are stainless steel.
