#1 Boiler Repair Plug

• Brand Name | Wal-Rich Corporation

Mark’s #1 boiler repair plug is a toggle designed for holes 3/8" or larger. To install, simply compress the spring and insert the toggle rod through the hole. Once the spring and toggle rod are inside, they automatically extend beyond the hole. Tightening the lock nut will compress the rubber washer against the outside surface for a leak-proof seal.
