Abstract
A bolt construction for use in an espagnolette locking system for the multi-point locking of sashes is made up of a linking rod (16) and a locking pin (17), one or the other of which is of fixed length and the other of which may be any one of a plurality of different lengths, the rod and pin being adapted to be connected together with a snap fit in any one of a plurality of different positions, thereby allowing the length of the interconnecting rod and pin to be chosen to fit a particular size of sash. The construction also provides a bolt construction for use in an espagnolette locking system for multi-point locking of sashes, which bolt construction is formed for assembly within a rebate in a face of the sash by means of a snap fit within the rebate. The construction also extends to a sash fitted with two such bolt constructions.
