CRL Standard Small Profile Windscreen Base Shoe for 3/8" or 1/2" (10 or 12 mm) tempered glass is typically used as the base channel for windscreens and privacy partitions. It is not recommended for Hand Rail/Guard Rail applications. Most standard glass windscreen applications use 3/8" (10 mm) monolithic tempered glass. Each glass panel is secured in the base shoe using CRL's Patented Dry Glazed TAPER-LOC® System. NOTE: If 1/2" (12 mm) glass is required, use CRL's Wet Glaze Method.
