All-Rack Black Cage Nuts

Black cage nuts are hardware used in computer racks and cabinets to secure equipment in place. 

They are made of steel and have a black coating to protect against corrosion and provide a sleek appearance.

Cage nuts are designed to fit into square holes on the vertical rails of a rack or cabinet. Once inserted, the cage nut's spring steel wings expand to grip the inside of the hole, creating a secure attachment point for screws.

Black cage nuts are commonly used in data centres, server rooms, and other IT environments where multiple pieces of equipment need to be mounted and secured. 

They are compatible with a wide variety of rack and cabinet types and can be used to secure servers, switches, patch panels, and other networking equipment.
