Box locker doors have a functional friction catch that permits the use of built-in locks or padlocks. All latch hooks have noise-reducing rubber bumpers. The door frames have mortise and tenon construction and are securely spot welded for lifetime rigidity. Every door has a vertical flange which creates a continuous door strike. All hinges are full loop, 5 -knuckle design, welded to the frame, and riveted to the door.
