The firestop electrical outlet box inserts and putty pads available at Discount Low Voltage provide a smart and easy way to help prevent the progress of fire, smoke and toxic gases in the event of a blaze. The intumescent material these products are made of expands when exposed to fire or heat, helping to seal off the spread of fire and its associated hazards.
Easy to install, these items are notable for their negatives as well as their positives. They don’t require tools to work with, and they leave no mess or residue. That makes it easy to do a clean, neat and professional job.
Used with metallic switch and receptacle boxes, our STI electric box inserts will permit firestopping of larger boxes and closer spacing. Available in assorted sizes, these inserts require no tools to install. Just peel and stick for insertions.
Our STI firestop putty pads are particularly appropriate for cable penetrations requiring occasional retrofitting. This non-hardening, intumescent compound can be externally applied to switch and receptacle boxes, and is ideal for sealing through-penetrations as well as certain membrane penetrations. The adhesive stays put and is not affected by humidity, condensation or water. Poly liners ensure a clean install with no muss and no fuss. These pads are available in a variety of sizes.
Common applications for these inserts and pads include single and multi-gang boxes, plastic and steel faceplates, and 1 and 2 hr. steel stud walls.
When in stock, these items typically ship in one business day.
One-step installation of these inserts and pads saves time and labor, and you need no special tools to use these products. Eligible items qualify for free shipping too.
