Description

Built for light‑duty commercial and auxiliary openings, this standard‑weight plain bearing hinge provides reliable, code‑compliant performance where traffic is moderate. The square‑corner heavy‑weight template pattern aligns with common door and frame preps for fast installation. Non‑rising pins keep doors true over time, while the optional Non‑Removable Pin (NRP) helps deter tampering from the secure side. Offered in stainless steel or steel in popular 4.5″×4″ and 4.5″×4.5″ sizes, it meets ANSI/BHMA A156.1 Grade 3 life testing up to 350,000 cycles and carries a UL10C fire rating up to 3 hours—ideal for offices, storage rooms, and residential‑style multifamily egress.
