The two-piece lockbox welds to matching points on the two container doors, encasing the padlock so only the shackle is reachable. Tack-weld to confirm alignment first, then weld out fully and paint. It suits insurance-type padlocks — where the pin and key are on the same side — and for best effect fit two: one at the top of the door and one at the bottom.
