The CRL B7S Series Heavy-Duty Square Base Shoe (SKU: B7S20D6) is a heavy-duty base channel designed for 3/4" tempered glass railing systems. Available with six architectural cladding finishes, this base shoe is engineered and tested for reliable attachment to concrete or steel substrates using CRL’s proven drilling patterns and fasteners.

Key differentiators:

• Designed specifically for 3/4" (19 mm) monolithic tempered glass — ideal for arena and stadium glass railing installations
• Pre-drilled 6" (152 mm) center-to-center pattern with custom drill options for project-specific layouts
• Available clad finishes protect the extrusion and simplify on-site finishing (recommended over direct powder coating)
• Custom cutting and mitering service for precise, job-ready base shoes

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" (3 mm)/-1/16" (1.5 mm) tolerance between holes. Before drilling installation holes in the substrate, place the base shoe in its final position and mark hole locations to ensure accurate anchoring.
