The CRL L21S Series Laminated Square Base Shoe is used as the base channel for glass railing systems. It can be clad in four 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 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.
GLASS SPECIFICATION:
For use with 27/32" (21.52 mm) Laminated Tempered Glass (10 x 1.52 x 10 mm)
Thickness Range: .803" to .903" (20.4 to 22.9 mm) Will work with ASTM 7/8" Monolithic Tempered Glass Will Not Accommodate the Full ASTM Thickness Range for 27/32" Glass
Product Warning:
CRL does not recommend direct powder coating of this base shoe extrusion. Powder coated cladding applied over the base shoe is the recommended method.
All pre-drilled CRL Base Shoes have a +1/8 (3mm) / -1/16 (1.5mm) tolerance between each hole drilled in the base. Before drilling installation holes in the concrete or steel substrate it is recommended that the installer place the base shoe into the planned final position, then mark the position of the holes to be drilled into the substrate.
