Fire-Rated Door Closers Built by Oude

A fire-rated door closer is a mechanical device that ensures a fire door closes and latches automatically after opening. Building codes require fire doors to remain closed during a fire to compartmentalize smoke and flames — a fire-rated closer is the component that makes this possible. Oude fire-rated closers are tested to UL 10C (3-hour fire resistance) and carry ANSI/BHMA A156.4 and EN 1154 certification, ensuring they continue functioning under fire conditions.

UL listing (UL 10C) is the North American standard that tests a closer's ability to keep a fire door closed during an actual fire — Oude closers pass the 3-hour (180-minute) test. EN 1154 is the European standard that defines performance classifications including closing force (En1–En6), opening resistance, and durability cycles. Oude closers carry both certifications, making them compliant for projects in North America, Europe, and international markets requiring either standard.

For surface mounted fire rated door closers, select based on door weight and width: 601-6BW or 301-6BW (En1–En6 adjustable) cover 15–150KG doors up to 1500MM wide — the most versatile choice. For lighter doors (25–85KG, ≤1050MM), the 5023AW (En2/3/4 selectable) or 6033AW (En3 fixed) are cost-effective options. For heavy metal fire doors (80–150KG), the 5055AW provides En5/6 closing force. All are UL 3-hour certified and support standard, parallel arm, and top jamb mounting.

Oude fire rated hydraulic door closers cover the full spectrum: light doors from 15–25KG, standard commercial doors from 25–85KG, and heavy doors up to 150KG. Door widths range up to 1500MM. The adjustable models (601-6BW, 301-6BW) cover the entire En1–En6 range, meaning a single closer model can be tuned to any door in your project. Concealed models (202-5BWH) handle 25–100KG up to 1200MM.

Yes. Oude's entire fire-rated door closer line is UL listed (COC R26448) and tested to UL 10C for 3-hour fire resistance on fire doors including metal fire doors. The 5055AW heavy-duty closer (En5/En6, 80–150KG) is specifically engineered for large metal fire doors in industrial and commercial applications. All models use hydraulic transmission closing technology with aluminum diecast bodies for long-term performance.
