Erico PRF3 Max Roller Support Size 3

Product Description

The ERICO PRF3 is a size 3 Max roller support designed to provide controlled, low-friction support for pipes, conduit, and other linear systems in mechanical and electrical installations. Roller supports allow supported lines to expand and contract with temperature changes without binding against the support structure. This type of hardware is a standard component in plumbing, HVAC piping, and industrial process piping where thermal movement must be accommodated. The PRF3 is sold as a single unit and is manufactured under the NVENT brand family.

The PRF3 is suited for commercial and industrial applications where piping or conduit runs require support at regular intervals while remaining free to move longitudinally. Typical install scenarios include rooftop mechanical piping runs, suspended ceiling pipe racks, and equipment room headers where thermal cycling is a routine operating condition. It is installed by licensed plumbers, pipefitters, and mechanical contractors working to project specifications.

Key Features

• Size 3 designation for compatibility with corresponding pipe or conduit diameters
• Roller design allows longitudinal movement to accommodate thermal expansion and contraction
• Sold as a single unit for flexible quantity purchasing
• Manufactured under the NVENT brand family

Compatibility

Designed as an OEM-style roller support for use in mechanical, plumbing, and electrical conduit installations requiring low-friction pipe support at size 3 designations.

Installation Notes

Installation is typically performed by licensed pipefitters, plumbers, or mechanical contractors. Follow applicable codes such as the IPC or IFGC for pipe support spacing and load requirements. Ensure the support structure is rated for the combined weight of the pipe, fluid, and insulation before securing the roller support in place. Depressurize and isolate any existing line before modifying support hardware on an active system.
