what are overnight locks

Its basically a cut down version of a multipoint lock I suppose you could say a euro case that can be installed in a UPVC door as a tempory measure until a replace unit can be order for the customer.
With so many different types of multipoint lock it is impossible to carry everyone in use. However there is a company that makes a universal lock that supposely fits most doors can't comment on the quality of this lock as I have never used it.
