This CRL 9BL68 Series Square Base Shoe is the same profile as our standard L68S 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, 9BL can be easily cut to the required length using a chop saw with a minimum 10" (254 mm) diameter blade for aluminum cutting.
