Abstract
Abstract A panel slider assembly for protecting verandas and exposed glass surfaces from wind damage and burglary attempts, comprising at least one panel slider of snap-lock construction, an inverted channel-shaped frame housing that extends along the entire bottom edge of the panel slider, a plurality of roller frames which are spaced apart within the frame housing and are equipped with horizontally disposed retention shelves, a bottom roller which is rotatably attached to each roller frame, a floor-mounted retention channel having a mushroom track upon which the bottom rollers travel and horizontally disposed retention lips which are higher and spaced closer together than the retention shelves, a downwardly disposed adjustment channel which is attached to the ceiling and within which the top portion of the wall panel slides, and at least two pairs of rotatably attached and horizontally disposed adjustment rollers which fend off the sides of the adjustment channels while permitting vertical movement of the panel slider therewithin.
