This CRL 8B Series Square Base Shoe is the same profile as our standard B7S Series, but it is 30% lighter, which means it is more price competitive, environmentally friendly, and will reduce your shipping costs. Designed to work with CRL's patented TAPER-LOC® System, 8B can be easily cut to the required length using a chop saw with a minimum 10" (254 mm) saw blade for aluminum.
