The Fluke GEO reel with 25m/82ft. of red wire cable is used to connect Fluke 1621, 1623, and 1625 testers to stakes for measuring earth ground resistance. The cable ends terminate with a banana plug and a connector to attach the earth ground tester to the Fluke earth stakes. The red cable reel has a hand crank on top of the reel for winding the cable back on the spool after use. The plug and the connector ends of the cable can be inserted into special slots on the reel to avoid unspooling of the wire.
