Portable management box, made of carbon steel, the default color is red, and yellow or brown can be customized upon request.
Each locking point on the box is secured with a single lock. Collect these keys and put them in the box. Then each authorized worker locks his own padlock on it. When the work is completed, Workers remove their padlocks from the box to get the key inside the box. For these two types of management boxes, the key inside can only be got after the last worker removes his lock.
