The Caraloc 640 Complete Exterior Door Lock for caravans.
To understand whether you require a left or right hand lock you'll need to decide if the door hinges are fitted on the left or the right hand side of the door, when facing the door from the outside. If the door hinge is fitted to the right then you will require a right hand lock and if the hinge is fitted to the left you will need to order a left hand lock.
