The SureLock™ B-Vent locking system keeps installed pipe from coming apart on the job, secures systems after installation, and allows for easy disassembly, says the manufacturer. A twist-locking system is used for quick assembly, and disassembly requires only a small screwdriver to disengage the SureLock, says the company. The locking system is standard on many popular 3-in. to 6-in. dia pipe, and it also twist-locks into regular B-Vent locking systems, according to the manufacturer.
