National Marker N222398 Zinc Square U-bolt 3/8 X 4 X 5 in

Product Description

The NATIONAL MARKER N222398 is a zinc-plated square U-bolt designed for securing pipe, conduit, or structural members to rectangular wood and metal surfaces. Built from steel wire with a zinc finish for corrosion resistance, this fastener measures 0.375 inches in rod diameter, 4 inches in width, and 5 inches in length. Each unit ships as an assembled box pack complete with a mounting plate and two hex nuts included, so no separate hardware sourcing is required. This is a catalog model 2192BC replacement-compatible fastener suited for general mechanical, structural, and utility installations performed by maintenance technicians, plumbers, and general contractors.

This square U-bolt is appropriate for residential and light commercial applications where pipe runs, electrical conduit, or structural members must be anchored to wood beams or metal channel. The square-bend geometry provides flush, stable clamping contact along flat and rectangular surfaces, making it a preferred fastener over round U-bolts in those scenarios. The zinc plating offers adequate corrosion protection for interior and sheltered exterior use. Minimum order quantity is 5 units per order.

Installation Notes

Installation is performed by maintenance technicians, plumbers, electricians, or general contractors depending on the application. De-energize any electrical systems and shut off fluid supply lines before working in proximity to existing utilities. Use appropriately sized wrenches to tighten the included hex nuts evenly to avoid cocking the mounting plate. Follow applicable local mechanical or building codes for fastener torque and spacing requirements when used in structural or pipe-support applications.
