National Marker N102921 Zinc Swivel Safety Hasp 4.5 in

Product Description

The NATIONAL MARKER N102921 is a 4.5-inch zinc swivel safety hasp designed to secure doors, cabinets, boxes, trunks, and similar enclosures. The ribbed body construction adds structural strength, and all mounting screws are fully concealed when the hasp is closed, preventing tampering with fasteners. A spring washer keeps the swivel staple locked in a fixed position at all times, allowing latching without a padlock. The unit is constructed of steel with a brass pin and weighs 0.375 pounds. This hasp suits facilities maintenance, lockout/tagout applications, and general hardware installation tasks across residential, commercial, and light industrial settings.

The N102921 is suited for use on a wide range of enclosures including utility doors, storage cabinets, equipment boxes, and trunks. The swivel staple design allows latching in the absence of a padlock, giving installers flexibility during setup or staging. The concealed-screw feature is particularly useful in security-sensitive environments where tamper resistance at the fastener level is a priority. Facilities technicians, electricians performing lockout/tagout work, and maintenance personnel are the primary installers of this hardware.
