The UAP Limited Tubular Latch is a high-performance door mechanism designed for professionals and homeowners seeking a reliable latch for internal doors that do not require a locking function. Its standout feature is its fire-door rating, offering peace of mind and compliance for 30-minute fire door assemblies, though users should ensure they select the correct backset size for their existing door handle configurations before installation.

No, this is a tubular mortice latch specifically designed for internal doors and does not include locking features.
UAP Limited products are built with high-quality standards; please refer to your specific point of purchase for detailed warranty terms.
Yes, this latch is approved to BS EN12209 standards and is suitable for use on 30-minute fire door assemblies.
Each set includes the tubular latch mechanism, a strike plate, a latch plate, and all required fixing screws.
Measure from the edge of the door to the center of the hole drilled for the door handle spindle. If it is 65mm, this is the correct size for your installation.
The finish is designed for indoor use. While durable, it is not specifically treated for harsh, direct outdoor weather exposure.
Check that the door is not warped and the strike plate is perfectly aligned with the latch bolt.
Ensure all fixing screws are tightened to the door surface and check that the internal spring mechanism has not been damaged during installation.
Verify the depth of the strike plate mortise; if it is too deep, the latch will not engage fully with the frame.
Installation requires a standard door mortice drill bit or a chisel to create the necessary pocket in the door edge. Ensure that the 65mm backset matches your door handle's spindle position. To maintain the mechanism, occasionally wipe the latch bolt with a clean cloth to remove debris. If the latch becomes stiff, a small amount of silicone-based lubricant can be applied to the latch head, but avoid heavy grease that might attract dust and grit over time. Always ensure the strike plate is aligned correctly with the door frame to prevent binding or misalignment.
