Abstract: A roller device for a sliding closure of the type which permits adjustment of the effective height of the sliding closure relative to its support frame after the closure has been installed within the frame is described. The device comprises first and second members adapted for sliding engagement within a channel of a side of the sliding closure, said members being connected by resilient means, the first member being adapted for removable, secure attachment to the sliding closure, the position of the second member being slidingly adjustable relative to the first member, the second member being adapted to slide along a track associated with an aperture within which the sliding closure can be installed and a recessed roller mounted for rotation within the second member for rolling along a top edge of the track.
