Description
The original! Our UNIQUE Split Sleeve Firestop System is designed to retrofit existing cable violations in a firewall with a re-enterable, multi-cable transit system. NO TOOLS REQUIRED. Instead of removing or rerouting cables, installers can correct the violation while keeping the existing cable infrastructure in place.
Our UNIQUE Split Sleeve Firestop System is a UL tested retrofit solution. It is designed for sleeving, firestopping and smoke sealing cables or wires already installed without a sleeve and in violation of the firewall rating. This zero-maintenance, through-penetration system is installed without any tools in minutes. No screws. No bolts & nuts. No clamps. No anchors. NO TOOLS REQUIRED. Saves time and labor. No need for installers to pull cables back out of the walls or floors after failing an inspection because the UNIQUE Fire Stop Split Sleeve design, a threaded, IMC conduit cut in half, can be fitted around existing cables.
A split sleeve firestop is a practical choice for retrofit projects where cables are already in place, and downtime is not an option. It allows installers to bring non-compliant penetrations up to code without disturbing the cables that support daily operations. With our threaded split sleeve firestop, contractors can reduce labor, avoid unnecessary delays, and move more efficiently toward inspection approval.
This Split Multi-Cable Transit System is UL 1479 Classified for up to 4 hours. Made in the USA.
