PICK THE FASTENER THAT MATCHES THE SIZE OF YOUR CHANNEL LETTERS.

We offer a full line of Clinching Machines made by Norlok Technology, Inc., the first company to design and produce them. Letterloks fasten letter backs to the returns of channel letters 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. It allows for a clean, safe work environment because it doesn’t produce fumes or heat and electrical hookups aren’t needed.

Channel letters come in various sizes, so we offer three different letterloks to suit your needs.
