Greenfield 417-1/2 Cushion Strut Clamp 5/8 Inch

Product Description

The GREENFIELD 417-1/2 is a cushion strut clamp designed to secure and support 5/8 inch piping and conduit in mechanical, plumbing, and HVAC installations. The cushioned insert isolates the pipe from direct metal contact, reducing vibration transmission and noise transfer to the surrounding structure. At 0.14 pounds, this is a lightweight clamp built for repeated use across multiple mounting points. Licensed plumbers, HVAC technicians, and mechanical contractors reach for this type of clamp when running pipe along strut channel in both residential and light commercial builds.

This clamp fits over standard strut channel and is suited for applications where pipe runs need firm, low-vibration support over long spans. Typical installations include hydronic piping, refrigerant lines, conduit runs, and domestic water supply lines routed along unistrut or equivalent channel systems. The cushion lining protects pipe coatings and helps prevent galvanic contact between dissimilar materials. Its compact footprint — 4.3 inches in length, 3 inches wide, and 2 inches tall — fits within tight mechanical spaces without clearance issues.

Key Features

• Cushion lining reduces vibration and noise transfer to structure
• Designed for 5/8 inch pipe or conduit
• Mounts directly to standard strut channel
• Compact dimensions: 4.3 x 3 x 2 inches for use in tight spaces
• Lightweight at 0.14 pounds — easy to handle during overhead installation
• Suitable for plumbing, HVAC, and general mechanical piping runs

Compatibility

Designed as an OEM-style replacement and general-use strut clamp for 5/8 inch pipe or conduit applications on standard strut channel systems in residential and light commercial mechanical installations.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians following local mechanical codes and applicable IPC or IMC guidelines. Shut off the relevant piping system and relieve pressure before repositioning or replacing clamps on active lines. Ensure the strut channel is properly anchored to structure before securing clamps. Do not overtighten the clamp hardware against the cushion insert, as this can compress the lining and reduce its vibration-damping effectiveness.
