Showcase Innovations’ Glass Clamp Assistant is designed for the purpose of holding the two-part glass clamp together while a screw is inserted and fastened, allowing a single glazier to complete an installation. The innovative tool is compatible with several types of shower enclosure glass clamps, including the CRL SCU4 and CRL BCU4, as well as the Cardinal and US Horizon equivalents. Manufactured in the U.S., the tool also assists in hole layout marking.
