The ROBROY KNRA-4 is a right angle conduit clamp designed for securing rigid metal conduit at 90-degree mounting positions to structural supports, walls, and channel. Constructed from malleable iron with a hot dip galvanized finish, this clamp resists corrosion in wet and outdoor installations. The 4-inch trade size accommodates standard 4-inch rigid metal conduit. It carries UL 6 and CSA C22.2 approvals and meets ANSI C80.1 standards, making it suitable for conduit support applications requiring listed hardware. Electricians and conduit installers use this clamp in commercial, industrial, and utility installations where right-angle support geometry is required.
The KNRA-4 is used in conduit support applications involving 4-inch rigid metal conduit, including industrial plant wiring, commercial electrical distribution runs, and utility infrastructure. The right angle design allows the clamp to mount flat against a wall, beam, or unistrut surface while maintaining perpendicular conduit orientation. The hot dip galvanized finish makes it appropriate for damp and wet-rated locations. Standard packaging is 10 units per carton, suited for project-quantity purchasing.
Designed for use with 4-inch trade size rigid metal conduit installations requiring right angle support clamp hardware per UL 6 and ANSI C80.1.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the work area before installing or adjusting conduit support hardware. Ensure the mounting surface is structurally adequate to bear the conduit load before fastening. Do not exceed the 10-pound load rating for this clamp.
