Hell in a Cell is a professional wrestling steel cage-based match which originated in 1997 in the World Wrestling Federation. It features a large cell structure, a five-sided cuboid made from open-weave steel mesh chain-link fencing which encloses the ring and ringside area. Unlike the steel cage match, the only way to get out of the Hell in a Cell without damaging the Cell's structure is through its door—but this door is locked by thick chains and a padlock. Only an in-ring pinfall or submission will ordinarily result in a win and there are no disqualifications. The gimmick was strongly associated with the Undertaker during his career with WWF/WWE, including the inaugural match with Shawn Michaels and a brutal encounter with Mick Foley in his Mankind persona. Both matches featured spectacular falls from the top of the cage which became a signature of the match.

A chain-link fence is a type of woven fence usually made from galvanized or linear low-density polyethylene-coated steel wire. The wires run vertically and are bent into a zigzag pattern so that each "zig" hooks with the wire immediately on one side and each "zag" with the wire immediately on the other. This forms the characteristic diamond pattern seen in this type of fence.
