Description

Core Bore Firestop System

Use our UNIQUE Core Bore Firestop System to cover, seal and firestop empty core holes in concrete slabs or walls during construction and post-construction. These core holes are often abandoned when sleeves or conduits in a concrete floor or fire-rated barrier are removed.

New Sizes! Now available in 1.5″, 2.0″, 2.5″, 3.0″, 3.5″, 4.0″, 4.5″, 5.0″, and 5.5″.

The Core Bore Seal you order needs to be 1/2″ smaller than the diameter of the core hole.

Easy to Install with NO TOOLS! For questions about choosing the correct size, installation or anything else, call our friendly expert Customer Service Support at 251-960-5018.

Our Core Bore Firestop System saves installation time and money while meeting all building codes. It is made of high-grade plate steel and a intumescent firestop muffin (plug). It comes with everything needed to install it except the firestop caulk. The Core Bore Seal is inserted into the hole and a bead of caulk under the top plate will smoke seal the Core Bore to the slab or wall. Our Core Bore Firestop System provides 100% firestop and smoke protection. The top plate can be covered by carpet. System may be  removed when the core hole is again needed but requires access to the floor below.

Installation Procedure

Select proper size Core Bore Seal by measuring the diameter of the empty core to be firestopped and sealed. Core Bore Seals come in 1/2 inch diameter increments for concrete slabs measuring between 3″ and 12″ thick. The Core Bore Seal you order needs to be 1/2″ smaller than the maximum diameter of the core hole. If you have any questions about proper sizing, please call our friendly expert Customer Service Support at 251-960-5018.

Clean the top edge of the core hole with a clean damp cloth to remove all dirt and debris so a good seal can be made.

Apply a 3/8 to 1/2 inch bead of intumescent fire stop caulk to the floor/wall where the Core Bore Seal will make contact.

Be sure the STOP sign is up and carefully place the Core Bore Seal in the core hole. The nut holds the system together and is not removed.  NO TOOLS REQUIRED. Step on it. Wipe away excess caulk. ALL DONE!
