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.

“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!”

“The best investment I made for my sign shop was buying my Computerized Cutters – Router, Model 26 channel letter bender and Clincher to build my channel letter business. It has been a blessing.
I really appreciate Carl inventing the bender. I have grown both the volume and more importantly the profitability of my channel letter business since I acquired these machines. And I can continue to grow my business with these machines. They are dependable and durable. Made in America – does mean quality where these machines are concerned.
I highly recommend your products to anyone who plans to grow their sign business. Your machines paid for themselves many times over! Great job!”
