Rated 5 out of 5 by from Mortice latch Good quality product very sturdy well made latch well worth the little extra cost. In the spec's section it says you need to drill a16mm hole to fit the latch it needs to be a 25mm hole.

Rated 5 out of 5 by from Amazing Bought these to fit to my internal 4 panel doors. Superb quality and the mechanism seems robust, plenty of sprung action to assist the operation of my door knobs. Satin chrome has never seen satin in its life, it's just chrome however that's what I was after so it worked out well for me. Another job well done

Rated 1 out of 5 by from Different satin chrome Sorry to say but this ‘satin chrome’ is not any where near a match for the satin chrome t bar handles from Smith&Locke with which I assumed it would match . There were also some components missing . It works BUT that is all I can say for it .

Does the latch open both clock- and anti-clockwise?

I need the latch to work either way and have a strong enough return spring as the knobs are not sprung.

What size hole do you need to drill in the door for it to accept the latch

Is this suitable for un-sprung heavy mortice door knobs.

Can you please advise whether these latches are suitable for use with un-sprung heavy mortice door knobs?
Asked by: Juhal
Hello Juhal, This will be suitable to use with a heavy Mortice knob by returning the knob on the spring. However one concern maybe the knob maybe difficult to turn especially if a person is frail. Thank you for using Q&A SW

Are these CE fire rated with a CE marking?

Asked by: Anonymous
Hello, Thank you for your enquiry. I think there maybe some confusion here, additional Intumescent protection is required for fire doors. Hope that helps. Thank you for using Q&A. MH
