S-5-U Mini Clamp

The S-5! U Mini Clamp is a compact, lighter-duty version of the S-5! U Clamp designed for standing seam metal roofs. It features one round-point stainless steel setscrew and no top bolt, making installation simpler and less costly while still providing secure anchoring for many rooftop accessories. Suitable for vertical and rotated horizontal seams (with appropriate seam widths), the U Mini is perfect for items like satellite dishes, signage, walkways, lighting, and conduit where full clamp strength is not required.

Key Features:

• Single round-point stainless steel setscrew (no top bolt included)
• Shorter clamp body than standard U Clamp for lighter-duty attachments
• Compatible with many standing seam profiles, used both vertically and rotated 90° for horizontal seams
• Non-penetrating design protects roof panel finishes and warranties
• Threaded holes in clamp body for ancillary attachment hardware

• Type: U Mini Clamp (non-penetrating, one setscrew)
• Material: Structural aluminum body; stainless steel setscrew hardware
• Seams compatible: Standing seam profiles with vertical orientation, OR horizontal seam profiles with horizontal projection ≥ 0.65″ (16.5 mm)
• Setscrew: One 3/8-24 × 0.80″ round-point stainless steel setscrew
• Approximate clamp body dimensions: length ≈ 1.50″ (38 mm), width ≈ 1.50″ (38 mm), depth ≈ 2.00″ (51 mm)
• Includes: Clamp body, one stainless setscrew, Torx-T30 driver bit tip

• Identify roof seam profile (standing seam, vertical or horizontal seam meeting width requirement).
• Position clamp body over seam so that setscrew aligns on seam surface.
• Insert the stainless steel setscrew and thread it by hand until it seats on seam.
• Tighten the setscrew using a Torx-T30 bit to specified torque (according to material and gauge).
• Attach accessory hardware using threaded holes in clamp as needed.
• Inspect alignment and re-check setscrew torque after initial loads (e.g. wind, snow, thermal changes).

Q: What differentiates the U Mini from the standard U Clamp?
A: U Mini is shorter, has a single setscrew instead of two, and does not include the top bolt, making it lighter duty and more economical.

Q: Can the U Mini clamp be used for snow retention systems like ColorGard?
A: No. Mini clamps are not compatible with ColorGard, SnoRail, or SnoFence snow retention systems.

Q: What seam profiles work with U Mini Clamp?
A: It fits many standard standing seam profiles; it works vertically or rotated 90° for horizontal seams with adequate projection (≥ 0.65″).

Q: What materials are used and how does this clamp protect roof warranties?
A: The body is structural aluminum; the setscrew is stainless steel. The round-point setscrew design compresses (dimples) but does not pierce the roof panel, preserving coatings and warranties.
