The ASEC Vital 6 Pin Rim Cylinder is a reliable choice for remedial installations, commonly paired with rim nightlatches on wooden doors. Designed for use on both fire-resistant and smoke control door assemblies, it features a secure 6-pin mechanism and comes with five keys and a fixing screw. This cylinder cannot be keyed alike with ASEC Vital 6 pin screw-in cylinders but can be matched with other Vital euro and oval cylinders. Available with a dual finish, it provides a practical solution for enhanced security in fire-rated door systems.
