Zephyr 5500 Club Series (5554/5570) Mechanical Locks

The 5500 Series Mechanical Lock is one of only two multi-user mechanical built-in locker locks on the market intended for steel lockers. Its improved security capabilities make it the perfect choice for shared-use settings in locker rooms, fitness centers, employee rooms, and other facilities. The shared use capability allows facilities to conveniently allow their visitors to choose their own combination while eliminating the need to distribute keys, combinations, or padlocks.

Designed and engineered with user experience in mind, our shared-locks have updated push buttons for improved user feel, fit perfectly in the recessed handles of steel lockers, and are available with different face plate colors to complement any type of locker.

The various locking options provide an extra level of security and ease of use with spring latch and dead bolt locking options. Users can have peace of mind and rest assured that their valuables will be safe with our secure locking solutions.
