Robroy KNRA-3-1/2 Right Angle Conduit Clamp 3-1/2 in

Product Description

The ROBROY KNRA-3-1/2 is a right angle conduit clamp designed for securing rigid metallic conduit to structural surfaces at a 90-degree orientation. Constructed from malleable iron with a hot dip galvanized finish, it provides strong corrosion resistance in exposed and outdoor electrical installations. Rated to a 10-pound load and built to a 3-1/2 inch trade size, this clamp is a fit for industrial and commercial conduit runs where a right angle mounting position is required. Licensed electricians and electrical contractors install this fitting as part of rigid conduit support systems governed by NEC guidelines.

The KNRA-3-1/2 is suited for use in commercial and industrial electrical installations where rigid steel conduit must be anchored at right angles to walls, beams, or other structural members. Its hot dip galvanized finish makes it appropriate for wet locations, outdoor raceways, and corrosive environments where standard zinc-plated hardware would not hold up. The 3-1/2 inch trade size accommodates the corresponding conduit diameter in EMT or rigid metallic conduit applications.

Key Features

• Right angle mounting design for 90-degree conduit support against structural surfaces
• Malleable iron construction provides durability and resistance to impact and vibration
• Hot dip galvanized finish delivers robust corrosion protection for wet and outdoor use
• 10-pound load rating supports conduit runs with standard fill
• RoHS compliant construction
• Meets UL 6, CSA C22.2, UL 2239, CAN/CSA C22.2, and ANSI C80.1 standards

Compatibility

Designed as an OEM-style support fitting for 3-1/2 inch trade size rigid metallic conduit installations in commercial and industrial electrical systems.

Installation Notes

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 mounting conduit supports. Ensure the mounting surface is structurally sound and capable of supporting the conduit load. Use fasteners appropriate for the substrate material when securing the clamp.
