The Accu-Clinch SPR Self-Piercing Rivet machine fastens channel letter returns to aluminum and aluminum composite material (ACM) as well as 1/8” Lexan letter backs. With the Accu-Clinch SPR, your operators can rivet a back to a standard 24-inch channel letter in a matter of minutes without pre-drilling and installing rivets. Reduces the time required to attach the return to the letter backs from about 12-15 minutes down to about 2-3 minutes.
The CLINCHER SPR gives you the ability to use the 4mm rivets for aluminum backs, and to use 5mm rivets with both ACM and Lexan backs.

“Our Clincher SPR just arrived and we completed what would have been a long days work attaching the letter backs to the returns in a couple of hours of the first day that we had it! This is exactly what we hoped the SPR would do for us. It is a great time-saver!
I’d recommend the Clincher SPR to anyone who fabricates channel letters!”
