MIRO 4-RAH-14 Roller Pipe Support - Supports Pipes up to 4" Inside Diameter & 4.5" Outside Diameter, Adjustable 4.5" to 14" Height

The MIRO 4-RAH-14 is an adjustable rooftop roller support built for 4 in. nominal pipe with up to 4.5 in. outside diameter. With an adjustable clearance range from 4.5 to 14 inches, it provides greater elevation flexibility while allowing pipes to move freely on a low-friction roller. Its durable, UV-stable polycarbonate base distributes loads evenly without roof penetrations, protecting membranes and extending roof system life.

Key Features:

• supports 4 in. nominal pipe up to 4.5 in. OD
• adjustable clearance range from 4.5 in. to 14 in.
• roller design accommodates axial pipe thermal expansion and contraction
• non-penetrating polycarbonate base protects roof membranes
• backed by a 20-year limited warranty

• Model / SKU: 4-RAH-14
• Pipe capacity: up to 4 in. nominal; maximum OD 4.5 in.
• Adjustable clearance: 4.5 in. to 14 in.
• Base dimensions: approx. 12 in. × 18 in.
• Footprint area: approx. 216 sq. in.
• Materials: UV-stable polycarbonate base, polycarbonate roller, galvanized hardware
• Load rating: up to 188 lb per support (evenly distributed static load)
• Recommended spacing: up to 7 ft on center depending on pipe size and load
• Design: non-penetrating, adjustable roller stand, allows free pipe movement

• plan the pipe run and determine required clearance.
• clean and level the roof surface where the support will sit.
• place the 4-RAH-14 base on the roof aligned with the pipe route.
• adjust roller height between 4.5 in. and 14 in. for required clearance.
• set the pipe onto the roller cradle, verifying smooth axial movement.
• repeat every 7 ft or as required by load and pipe size.
• check alignment, stability, and distribution across all supports.
