Appleton UBC150 Conduit U-bolt 1-1/2 in Heavy-duty

Product Description

The APPLETON UBC150 is a heavy-duty, round-bend conduit U-bolt designed to secure Rigid Metal Conduit, IMC, or EMT to beam, channel, and angle supports. Built from malleable iron with a mechanically galvanized finish for corrosion resistance, this U-bolt is rated for trade size 1-1/2 inch conduit. The fastener features a 5/16-inch nominal bolt diameter with 18 TPI UNC threading and a thread length of 1.5 inches. It includes a hex nut and is engineered to withstand heavy structural loads in commercial and industrial electrical installations. Licensed electricians and conduit installers use this fitting where rigid support and durable hardware are required.

The UBC150 is suited for residential, commercial, and industrial conduit runs where Rigid Metal Conduit, IMC, or EMT must be secured across, parallel to, or perpendicular to structural steel members including beams, channel iron, and angle supports. The round-bend geometry conforms closely to the conduit OD, providing a secure, stable clamp without deforming the raceway. It is commonly installed in exposed conduit systems on unistrut channel or structural steel framing in mechanical rooms, industrial facilities, and commercial construction.

Compatibility

Designed for use with 1-1/2 inch trade size Rigid Metal Conduit, IMC, and EMT. Suitable for installation across, parallel to, or perpendicular to beam, channel, and angle structural supports.

Installation Notes

Installation is performed by licensed electricians in accordance with the NEC and applicable local codes governing conduit support spacing and fastening methods. De-energize all circuits in the conduit run before beginning support work in live areas. Ensure the U-bolt legs pass fully through the support structure and that the hex nut is tightened securely against the bearing surface without overtightening, which can distort the conduit. Use appropriate hardware for the support substrate — do not substitute undersized nuts or washers.
