S-5-H Mini Clamp

The S-5! H Mini Clamp is a two-piece, lighter-duty clamp designed for metal roof panels with horizontal seams that are not fully closed. It’s shorter than the standard H Clamp and uses a single Torx T-30 round-point side setscrew for gripping the seam. It accepts the same insert piece used on the standard H to fit wider seams up to 0.75″ (19 mm). The clamp doesn’t include the top M8 bolt (which standard H does). It is suitable for lighter rooftop accessories like signs, satellite dishes, conduit, lighting, and similar applications.

Key Features:

• Two-piece clamp design for horizontal seams not fully closed
• One side-installed T-30 Torx round-point setscrew instead of two
• Fits seams up to 0.75″ (19 mm) with insert piece
• Shorter body than standard H Clamp, for lighter-duty attachments
• Doesn’t include the top M8 bolt; used for accessories rather than heavy structural loads

• Compatible panels: Standing seam panels with horizontal seam orientation (single-folded)
• Setscrews: One 3/8-24 × 0.80″ T-30 round-point setscrew
• Seam width accommodation: Up to 0.75″ (19 mm) with insert included
• Insert type: Same insert used with standard H Clamp to fit wider seams
• Includes: One H Mini unit (aluminum body, insert piece, single setscrew; bolt not included)

• Position clamp body onto the vertical leg of a horizontal seam.
• Slide the insert piece into clamp if seam is wider than nominal.
• Tighten the single side-setscrew with a Torx T-30 driver to specified torque.
• Install accessory if needed, using any separate hardware.
• Check that the clamp is secure and that seam finish is not deformed.
• Periodically inspect clamp for tightness and integrity, especially after thermal expansion or weather events.

Q: What is the difference between H Clamp and H Mini Clamp?
A: H Mini is shorter, lighter duty, with one setscrew instead of two, and lacks the top M8 bolt.

Q: Can H Mini Clamp be used for ColorGard or snow retention?
A: No. The Mini version is not compatible with snow retention systems—standard H should be used for that.

Q: What maximum seam width does H Mini accommodate?
A: Up to 0.75″ (19 mm) with the insert piece.

Q: Is the top M8 bolt included with H Mini Clamp?
A: No. The H Mini does not include the accessory bolt; that is part of the standard H Clamp.
