Beckson: Channel-Mate Glass Channel

Made of B-FLEX marine plastic, it will not crack or discolor. It is resistant to all weather and salt spray and is non-corrosive. The window grooves are slightly narrower than the window glass. Thus, there is a positive pressure against the glass at all times to seal out leaks and to prevent rattling. The elevated slide at the bottom of the channel makes opening and closing windows and doors a breeze. Also ideal for installing sliding cabinet doors . 8' lengths.  For 1/4" glass.
