A sliding fire door is a certified assembly—not just a steel panel on a track. This guide explains how sliding fire doors close automatically to contain fire and smoke, covers UL 10B, NFPA 80 Type 8/10, and EN 16034 standards, and shows how to specify compatible hardware correctly.

A fire-rated hinge label alone doesn’t guarantee compliance. This guide explains how ANSI/BHMA A156.1, EN 1935, UL 10B/10C, CE marking, and NFPA 80 each address different requirements—hinge performance, assembly testing, or installation—and how to verify hinges against your specific door assembly’s listing.

The best hospital door closer isn’t the strongest one—it’s correctly sized for door weight, traffic, and pressure while remaining accessible. This guide covers Grade 1 surface closers, parallel-arm vs. track configurations, ADA opening-force limits, and fire/smoke-door compliance for patient rooms, corridors, and emergency exits.

A premium lever can’t compensate for an incompatible latch. This guide compares tubular, cylindrical, mortise, privacy, and passage latches, explains backset and spindle measurement, and covers ANSI/BHMA and EN 12209 certifications for residential, commercial, and fire-rated door applications.

A door cylinder isn’t a complete lock—it drives the lock case. This guide compares Euro, mortise, rim, and interchangeable-core cylinders, explains precise A/B sizing measurement, and covers security features, materials, and EN 1303:2026/ANSI-BHMA certifications for residential, commercial, hotel, and high-security applications.
