This Loops 76mm Bolt Through Tubular Door Latch in Silver is designed for residential and commercial doors requiring a secure and reliable latching mechanism, particularly for lever handles on rose fixings. Its key benefit is the integrated bolt-through facility which simplifies installation and ensures a robust fit. A potential consideration is its specific 76mm size, which may not fit all existing door cutouts without modification. This latch offers durability, fire safety compliance, and straightforward installation for a variety of door types.

The bolt through facility allows the screws or bolts from lever handles (specifically those on rose plates) to pass directly through the door and the latch mechanism. This provides a much more secure and stable fixing for the handles compared to standard spindle-based fixings.
While designed for durable operation, its suitability for exterior doors depends on environmental factors. The nickel plate finish offers some corrosion resistance, but for highly exposed coastal or very humid areas, additional protection or a more specialized finish might be preferable. It is commonly used for interior doors and some sheltered exterior applications.
CE marking indicates that the product conforms to applicable European Union directives for safety, health, and environmental protection. For this latch, it signifies it meets relevant performance and safety standards required for sale within the EU.
This latch is specifically designed for lever handles with bolt-through fixings. It is not compatible with standard spindle-operated door knobs, which require a different type of latch mechanism.
The pack includes the 76mm tubular latch, round forends, a corresponding strike plate for the door frame, and a plastic dust box.
The 76mm measurement typically refers to the backset – the distance from the edge of the door to the center of the spindle hole. Measure your existing latch's backset or the prepared door cutout to confirm compatibility. This is a common size for many doors.
The product comes with a 5-year mechanical guarantee, covering defects in the materials and workmanship of the latch mechanism itself.
Ensure the door is not swelling or warped. Check that the latch mechanism is clean and free from debris. Verify that the lever handles are properly tightened and aligned with the latch spindle.
Check the alignment of the strike plate on the door frame. Adjust the strike plate position or file the opening slightly if necessary. Ensure the door is hanging correctly and not sagging.
Confirm that the correct size bolts are being used for the door thickness and handle roses. Ensure the holes drilled for the bolt-through fixings are not too large. If the door material is soft, consider using wood inserts for a more secure fit.
The mortise for the latch and forend plate may need to be deepened slightly. Ensure no obstructions are preventing the plate from seating correctly.
