Description
Securing your restricted access doors is simple with the Carbine 4000 Sandown Vestibule Lockset. Specifically engineered for commercial entryways, store rooms, and secure residential access points, this heavy-duty tiebolt lockset provides automatic locking from the outside. Consequently, it serves as an ideal replacement for worn-out vestibule and storeroom locksets across standard Australian timber and metal doors.
Automatic Exterior Locking with Always-Free Egress
The Carbine 4000 Sandown vestibule lockset features a dedicated single-action security function. Outside, the knob remains permanently locked to prevent unkeyed entry. Inside, the knob remains unlocked at all times for immediate exit during emergency situations. Furthermore, operating the key from the outside retracts the latch temporarily without unlocking the external handle. As a result, you maintain complete perimeter security without relying on manual locking turn-knobs.
Concealed Tiebolt Mounting & Easy DIY Retrofitting
Installing the Carbine 4000 Sandown vestibule lockset requires basic hand tools. Specifically, this hardware utilizes a concealed tiebolt mounting system. Fixing screws remain hidden beneath the internal rose plate, protecting the lock against forced tampering or loosening. In addition, the latch bolt adjusts smoothly between 60mm and 70mm backset measurements. Consequently, it fits standard Australian 54mm cross-bore door preparations without requiring extra chiseling.
Standard C4 Keyway & Master Keying Compatibility
Every Carbine 4000 Sandown vestibule lockset comes equipped with a rekeyable 6-pin C4 brass cylinder. Therefore, a licensed locksmith can easily key this lock alike to match your existing entrance deadbolts or master key systems. As a result, you can integrate this lockset seamlessly into commercial facility suites using a single key profile.
