The Dzina Tubular Latch 100mm is a professional-grade door hardware solution designed for contractors and homeowners seeking a secure, long-lasting mechanism for internal doors. Its primary benefit is its exceptional durability, having been tested to 50,000 cycles, and its fire safety compliance; however, users should note that the 82mm backset requires specific door furniture dimensions to ensure proper alignment and fit.

Yes, it is 60-minute fire rated, making it suitable for use on doors requiring fire protection.
The Dzina Tubular Latch features an 82mm backset.
It means the latch is designed with holes that allow screws to pass through the latch body to fix two handle plates together from both sides of the door.
Yes, every pack includes the necessary keeper for the door frame.
It is CE approved to BS EN12209:2003 standards.
This product is typically designed for internal door applications; please check local building codes for specific external door hardware requirements.
Check that the door is not binding against the frame and ensure the latch is installed perfectly level within the door edge mortise.
Verify that your door furniture is compatible with the 82mm backset and that the bolt-through holes are aligned with the designated slots on the latch body.
Ensure the handle spindle is the correct size and is not bottoming out against the latch mechanism internally.
For installation, ensure you have measured the distance from the edge of the door to the spindle hole to confirm it accommodates the 82mm backset. Use a chisel to recess the forend into the door edge so that it sits flush. When installing, ensure the keeper is precisely aligned with the latch bolt on the door frame to prevent friction. To maintain the mechanism, avoid using harsh abrasive cleaners on the silver faceplate; a soft, dry cloth is sufficient to keep the hardware in good condition. Periodically check that mounting screws remain tight to preserve the integrity of the handle connection.
