FAQs
What is the backset of this latch?
This latch has a fixed backset of 55mm.
Can this be used on fire doors?
The product is CE certified, but always check your local building regulations and the door manufacturer's guidelines regarding fire-rated hardware.
What tools are needed for installation?
You will need a drill, a 25mm spade bit, a screwdriver, a sharp chisel for the mortise, and a measuring tape.
Is the strike plate included?
Yes, the latch comes with the necessary matching strike plate for the door frame.
Does this latch have a privacy function?
No, this is a standard tubular latch. It does not include a locking mechanism.
Can I use this with traditional knob handles?
Yes, provided the handles support the bolt-through mechanism.
Troubleshooting
Latch tongue does not retract fully
Check that the latch body is not being pinched by a tight mortise and that the door is not warped.
Handle feels wobbly
Ensure that the bolt-through screws are tightened securely and that the handles are properly aligned with the latch holes.
Door fails to latch securely
Verify that the strike plate is aligned correctly with the latch tongue; adjust the strike plate position if necessary.

Setup, Compatibility & Care
Installation Steps
- Mark the center point for the latch hole on the door edge and the handle spindle hole on the door face.
- Use a 25mm spade bit to drill the hole for the latch body into the door edge.
- Mortise the door edge so the 56mm forend sits flush with the surface of the door.
- Insert the latch and secure it using the provided screws.
- Align your handle set and ensure the through-bolts pass cleanly through the latch body holes.
Compatibility
This latch is designed for standard interior doors. Ensure your door thickness is sufficient to accommodate the 75mm body depth. It is compatible with most standard lever-on-rose or knob-on-rose sets that support bolt-through fixings.
Care
Keep the latch mechanism debris-free. If the operation becomes stiff over time, apply a light, non-corrosive silicone-based lubricant to the latch tongue. Avoid harsh chemical cleaners on the silver forend; a soft, damp cloth is sufficient for cleaning.
