The Elimination Chamber is a professional wrestling elimination-based match held in the WWE promotion. It features a large chain-linked circular steel structure or “chamber” which encloses the ring. The chamber’s floor is platformed over the ringside area which elevates it to ring level and within the chamber are four inner enclosures outside each ring corner. While similar in profile and nature to WWE’s original large scale steel-structured match, Hell in a Cell, the Elimination Chamber match is strictly a six participant match wherein two participants begin the bout in the ring as the remaining four are held within each inner enclosure and are released into the match at five minute intervals.
The objective is to eliminate each opponent from the match via pinfall or submission. The winner is the last remaining participant after all others have been eliminated. As in the Hell in a Cell match, disqualifications do not apply. The structure itself is 16 ft (4.9 m) high, 36 ft (11 m) in diameter, weighs over 10 short tons (9,100 kg), and comprises 2 mi (3.2 km) and 6 short tons (5,400 kg) of chain. There have been sixteen Elimination Chamber matches in WWE since the concept’s inception in November 2002. (Courtesy of Wikipedia.com)
