Allows for variation management in critical joints. This is achieved with a heat-treated floating nut inside a weldable cage.

Our cage nut design allows for welding of the fastener into the desired location, allowing movement in all axis. "Lift Tabs" are located on the bottom of the cage to reduce secondary coating operations from adhering.

Gripco® cage assembly products come in two versions. One is open on the top, allowing for replacement of the fastener. The other is encapsulated after being welded (inverted), allowing for the reuse of the fastener after disassembly.
