Electronic Combi Lock with Flat Top These six-door lockers are a convenient solution to personal storage problems. An electronic combination lock mechanism secures reinforced doors for safe and secure storage of wallets, mobile phones and other personal effects. The lockers have a durable steel frame and are coated with an anti-bacterial agent resistant to MRSA and E-coli. The lockers are free-standing but pre-drilled holes to the rear of the units mean they can be secured to walls for added safety and stability.
