Miro Industries 3-rah-8 Roller Bearing Rooftop Support

Product Description

The MIRO INDUSTRIES 3-rah-8 is a roller bearing rooftop support designed to provide stable, low-friction pipe and conduit support on commercial and residential rooftop installations. Roller bearing supports reduce movement stress on piping systems by allowing controlled linear expansion and contraction without binding. This type of hardware is commonly installed by mechanical and plumbing contractors during new construction or re-roofing projects where pipe runs are exposed to rooftop conditions.

The 3-rah-8 is suited for rooftop mechanical systems where pipes, refrigerant lines, or conduit runs require support above the roof surface. It accommodates thermal movement in the supported line, making it appropriate for HVAC suction and liquid lines, plumbing vents, and similar rooftop pipe runs that experience temperature-driven expansion cycles.

Key Features

• Roller bearing design allows controlled axial pipe movement to accommodate thermal expansion
• Rooftop-rated support configuration for exposed outdoor installations
• Reduces stress at pipe hangers and connections caused by linear movement
• Applicable to refrigerant lines, plumbing piping, and conduit rooftop runs

Compatibility

Designed as an OEM-style rooftop pipe support for use in commercial and residential rooftop mechanical installations where roller bearing pipe support is required.

Installation Notes

Installation is typically performed by licensed mechanical, plumbing, or HVAC contractors. Shut down all affected systems and relieve line pressure before servicing or repositioning rooftop supports. Fastening to roof substrate should comply with applicable building codes and roofing manufacturer requirements to avoid membrane damage. Follow SMACNA or local mechanical code guidelines for support spacing on rooftop pipe runs.
