Locking Case with permanently depressed Snib -

[crusaderman]

I have just replaced a broken central locking mechanism for a customer. This lock is an ABT Gibbons locking case which can either be used as a stand-alone or connected up to a pair of shoot bolts via the usual linkages.

The lock has an anti-slip snib directly above the latch and pokes through the supplied 220 mm long face plate.

This face plate was discarded and the old full length face plate was used with the existing shoot bolt linkages.

The old longer face plate does not have a slot or opening in it to allow the snib to pass through it and so therefore the snib is now permanently depressed which means the handle has to be turned every time the door is closed (not ideal).

Anyway apart from this slight inconvenience, I was wondering if this set up might have any detrimental effect on the inside workings of the casing or putting any unnecessarily load on them? I'm thinking the snib is being compressed more than it should be , i.e. the thickness of the face plate.

I only ask this as the original lock I replaced had broken around the square spindle rendering it useless. I have also noticed that the key feels notchy when turning it even though all the bolts slide freely into their respective keeps.

Compressing the snib was something of an oversight on my part, but having realized this had happened I didn't want to have to dismantle and take this out as it would have invalidated the guarantee

Drill a hole and file it square so the snib can protrude, or remove it entirely. Otherwise the latch will get a pounding everytime the door is closed.

Thanks for your advice MHole. The cut out hole for the snib was exactly what I was thinking of doing. Removing the snib involves opening the casing which would be the wrong option for more than one reason.

I agree with Mhole. Can you use th old face plate or use it as a pattern to cut out the slot?
