UNIQUE Fire Stop Products has manufactured and sold firestop systems for both new and existing construction since we invented and patented the original Smooth Firestop System and the Split Sleeve Firestop in 1997 and 1998. Firestopping data cables and wires is still our only business and we continue to invent revolutionary products to help installers solve today’s firestopping issues. If you need to firestop cabling, we have a system for it. Manufactured in the USA in our own factory, we guarantee the highest quality fit and finish on the market. We understand that each situation is different, and we offer friendly, expert Customer Service to help you choose the right system for your needs. If we don’t have it in stock or in the size or configuration you need, we will custom manufacture it and ship it to you within 24 hours. Call us today at 251.960.5018 or send us an email.

I watched the firestopping video and looked at Fire Stopping By the Numbers and it helped a lot. I thought this was a very informative site, loaded with useful information. Until I got a Construction Coordinator position here at Time Warner Cable I didn’t realize there was so much to know about fire stopping techniques.
