Brass Bi-Fold Door Top Guide Roller

The National N182-790 is a brass top guide roller designed for bi-fold door systems. It provides smooth tracking and alignment for folding door panels in residential settings. Homeowners and installers use this hardware to maintain proper door operation. The component replaces worn or damaged original rollers on compatible tracks.

Simple Track Installation

Installation involves seating the roller into the existing top track channel of the bi-fold assembly. No specialised tools are typically required beyond basic hand tools for door adjustment. The brass construction resists corrosion during handling and fitting. Ensure the track is clean and free of debris to prevent binding or premature wear after installation.

Standard Bi-Fold Weight Support

The roller supports standard residential bi-fold door panels within typical weight ranges for this hardware class. It handles daily cycling reliably when the track is straight and correctly aligned. Excessively heavy panels, bent tracks, or misaligned jambs will exceed the roller's capacity and cause failure. The brass material offers durability for normal interior folding door use.
