Why OneFermeture exists
Every lock, hinge, and closer we list is checked against actual door frames, fire codes, and daily traffic. You get fittings that install cleanly, meet safety standards, and keep working after years of heavy use.
Who We Are
Every product we list is checked against standard door thicknesses, backset measurements, and fire-rated assembly rules before it reaches the catalog. If a lock does not fit a common frame profile, we say so in the specification sheet rather than hiding it in fine print.
Compatibility notes for each itemPanic bars, electromagnetic locks, and closers are evaluated for emergency exit codes and fire door regulations first. We document the relevant standards on each product page so facility managers can verify the hardware against local inspection requirements.
Safety standards listed per productOur team has installed enough cylinder locks and exit devices to know where alignment issues appear. We include practical guidance on spindle lengths, strike plate positioning, and power supply needs for electronic entry systems, so the hardware works the first time.
Field-tested installation guidanceWhen you contact us about a lock or access control unit, you reach someone who can discuss pin counts, latch throw, and voltage requirements. We do not route you through generic customer service scripts; we answer with the technical detail your project needs.
Direct technical support deskProperty managers often handle residential blocks and commercial units with different security levels. Our catalog covers both ends, from mechanical euro cylinders for apartment doors to heavy-duty panic bars for retail exits, with clear guidance on which product suits which setting.
Residential and commercial coverageEach product page includes a specification sheet, a compatibility guide, and a short note on maintenance. We keep the language plain and the measurements exact, so you can compare options without decoding marketing terms.
