The CRL B7S Series Heavy-Duty Square Base Shoe is used as the base channel for glass railing systems. It can be clad in six choices of architectural finishes. The most critical component in a railing system is the proper attachment of the Base Shoe to the substrate. CRL has engineered and tested a variety of attachment methods, and has developed an acceptable combination of drilling patterns and fasteners. A printed brochure with instructions, installation hints, cleaning, and refinishing techniques is available.
3/4" (19 mm) Thick Glass when using TAPER-LOC® Dry Glaze System or Wet Glaze System.
Product Warning:
All heavy Base Shoes have a stock length tolerance of plus or minus 3/4" (19 mm).
CRL does not recommend direct powder coating of this base shoe extrusion. Powder coated cladding applied over the base shoe is the recommended method.
