The new SureLock™ B-Vent Locking System is now on 90-degree adjustable elbows and 45-/60-degree adjustable elbows in the 3- to 6-inch sizes. The lock design makes installations fast and foolproof, allows for easy disassembly, and eliminates any need for screws at the joints, says the manufacturer. Installation is accomplished by joining elbows to sections of the company’s B-vent, then twisting and engaging the SureLock. Only a small screwdriver is needed to disengage the locking system.
