Detailed Product Description:

Exceptional Fire Door Hardware Compliance

The Certifire tubular latch has been independently tested and certified according to rigorous UK and European fire safety standards. This architectural-grade tubular latch ensures your doors meet mandatory regulations for fire-resisting applications such as FD30 and FD60 timber fire doors. Achieving CE marking and full Certifire approval demonstrates the latch’s ability to maintain integrity and function under fire conditions, which is critical in both residential and commercial fire escape routes.

Precision Backset Options for Perfect Fit

Available in three precise sizes—63mm, 76mm, and 100mm—the Certifire tubular latch range suits a broad spectrum of door setups. The backset measures the distance from the door’s faceplate to the spindle center, ensuring correct handle placement and ergonomic use. The 63mm latch suits compact doors or narrow frames, the 76mm is a popular mid-range choice for most internal doors, and the 100mm model fits larger or more robust door styles commonly found in commercial settings.

Superior Mechanism for Smooth Operation

Inside the latch body, a sophisticated double-sprung mechanism provides heavy-duty performance and smooth door latching. One spring supplies the main resistance ensuring the latch bolt returns reliably after usage, while a secondary lightly sprung latch bolt smoothly engages with the strike plate to hold the door securely closed without excess friction or noise.

This thoughtful engineering delivers consistent, trouble-free function even with frequent door usage in busy environments such as offices, hotels, and public buildings.

Reversible for All Door Handings

Flexibility is built in with the reversible latch design. Installers can quickly adapt the latch to function on either left or right-hung doors simply by twisting the latch case 180 degrees. This feature reduces the need for different stock types and speeds up installation on site, making the Certifire tubular latch a practical choice for contractors and maintenance teams.

Robust Build and Finish Options

Crafted from strong metal alloys including steel or brass components, these latches are finished with corrosion-resistant coatings such as satin chrome or antique brass. This ensures they not only perform well but maintain a professional, polished look over time despite exposure to daily wear or climatic conditions.

With bolt-through fixing holes provided for most sizes, the Certifire tubular latch offers secure, durable installation compatible with a variety of architectural hardware designs.
