National Mfg N131-565 Adjustable Door Guide Zinc

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N131-565 is a zinc-finish adjustable door guide built for single sliding and bi-parting metal or wood doors in demanding agricultural and industrial environments. Manufactured from hot rolled steel, this guide is engineered to withstand repeated impact from trucks, tractors, and farm machinery without failure. A smooth ramp on each side of the guide deflects contact from tractor and truck tires, preventing cutting or damage during normal farm or factory traffic. Licensed contractors and experienced installers working on agricultural or commercial sliding door systems are the primary installers of this hardware.

This door guide is intended for use around factory buildings and farm structures where heavy equipment traffic passes near door openings on a regular basis. It mounts directly to concrete floors using lag screws and shields, or secures to a 6 inches x 6 inches post for above-grade installations. A 0.5 inches rod or bolt inserted through the hole on each side of the guide functions as a center stop for bi-parting door configurations. The guide meets ANSI/BHMA 156.14 standards for door hardware, confirming dimensional and performance compliance for commercial and agricultural applications.
