Description

Engineered for demanding openings, this heavy‑weight ball‑bearing hinge delivers smooth, long‑life performance on high‑traffic, fire‑rated doors. The four‑bearing stack minimizes friction and sag, while non‑rising pins with button tips maintain alignment under load. An optional Non‑Removable Pin (NRP) deters pin extraction from the secure side, making it ideal for healthcare, education, hospitality, and commercial facilities. Square‑corner, heavy‑weight template prep ensures drop‑in compatibility and fast installation across common door/frame preps.
