Gate Keeper Double Link GM D3003 F6

The Double single link is used with the U-Bolt (GM U1001) to allow a double padlock solution.  Made of carbon steel, roto blasted, hardened, and plated for many years of use and backed with our limited lifetime warranty.  The hole open is 1/2" diameter which will fit all padlocks, including the Knox Lock which fire departments recommend and require in many cases.
