We offer a full line of Clinching Machines made by Norlok Technology, Inc., the first company to design and produce them. The Letter Lok is designed to fasten letter backs to the return of channel letter by clinching, which eliminates the need for fasteners or adhesives. Clinching increases production by quickly, consistently, and expertly fastening together different materials of different thicknesses. In addition, it allows for a clean, safe work environment because it doesn’t produce fumes or heat, and an electrical hook-up is not needed. Channel letters come in various sizes, so we offer different letter loks to suit your needs.
