CRL Roman Series Fixed Panel U-Clamps are used to secure fixed panels of glass to walls, floors, and ceilings. The rounded corners give the clamp a "softer" design and creates a classy look. One mounting screw per clamp is included. They perform the same function as our Standard Fixed Panel U-Clamps. They are especially recommended for 1/2" (12 mm) thick glass installations where a hole drilling measurement of 1-1/2 times the glass thickness (from the edge of the glass to the closest edge of the hole) is required. Custom finishes are available on request by contacting CRL Technical Sales Shower Door Department.
