Abstract

There is described a roller assembly which is adapted to be snapped into and out of a channel of a sliding frame closure which device is used to adjust the effective height of the closure relative to an aperture frame in which it is installed. The roller assembly or device comprises an outer stationary frame member having a pair of correspondingly positioned canted slots formed therein and means provided on the outer frame member to permit frictional and mechanical engagement of the assembly within the channel of the sliding frame closure; an inner frame member adapted to be mounted within the outer frame member and having at least one roller wheel fixedly mounted therein for rotation about its axis; the inner frame member being mounted for vertical movement within the outer frame member by means of a transverse pin which extends through the canted slots of the outer frame member; the inner frame member being secured by adjustment means to the outer frame member such that on tightening of the adjustment means, the transverse pin secured through the inner frame member slides down the canted slot moving the roller wheel vertically downward and reverse movement occurs on loosening of the adjustment means. Also described is the combination of at least one of the roller assemblies and a sliding frame closure.
