A packer for use, for example, in locating a lock keep (30) relative to a profile member (37) from a door or window frame comprises a body (10) with a number of spacer members (11) projecting from the body (10). The spacer members (11) can be selectively folded over to engage with the body (10) to provide various packer configurations. For example, spacer members (11) can be folded over to form slots to locate on either side of flanges (39a, 39b) provided on the profile (37).
