We are having some patio doors fitted and they are rebated.

  • The doors open outwards
  • The left-hand door opens first

We would like to fit a narrowstile lock with a roller (rather than a catch) and I do not know the answer to the following:

  1. Which door should the lock be set into?
  2. Rebate kits for locks come in left-handed and right-handed form. Given that I have a roller lock, do I care about whether I need a left- or right-hand rebate kit?

'rebate' means something entirely different on this side of the pond. I wasn't aware of that English/American difference. –  DA01 Dec 13 '11 at 15:15

The roller doesn't affect how you select and install the lock. Think of it as of a latch of weird form.

The conventional way would be to install the lock onto the door that opens first such that when you are in front of the door and the door that bears the lock has hinges on the right you have to rotate the key clockwise to unlock and counter-clockwise to lock and if the door has hinges on the left you rotate the key clockwise to lock and counter-clockwise to unlock.

This answer has great pictures for door opening directions.

The latter is all about "right-handed" v "left-handed" - with the lock selected correctly you will have it behave conventionally. You can of course install the lock with "wrong" rotation direction (right-handed where a left-handed should go or vice versa) - then it will work okay, but you will have to rotate the key opposite to convention which is a bit annoying. That's the only issue you might have - it has nothing to do with the roller.
