A hasp & staple is a locking mechanism used on a door or cabinet and held in place with a padlock or pin. Used on a wide range of buildings & outbuildings, including garages, sheds, workshop's, barns, storage cabinets and boxes. Can also be used on the doors of vans and commercial vehicles.

The hasp part of the lock has pre-drilled holes enabling it to be screwed to the door and has a hinged strap attached to it containing a slot. The staple is a metal loop which fits on the adjacent door, frame or lid. The hinged strap on the hasp slots over the staple and is secured in place by a padlock, pin or tumbler.
