The newer (circa 1830) of the pair at Lock No 62 on the Trent and Mersey Canal is in use on the right. The original (circa 1776) lock to the left is not in use, and acts as a weir to allow surplus water an overflow channel.

The eight paired locks forming the Wheelock Flight allow a rise in water level of 79ft 6in (24·2 metres). This is one of the fifth pair up. The flight is also part of the more extended series of twenty-six locks, many also paired, which make up the Cheshire Locks, or "Heartbreak Hill" as the canal climbs towards Kidsgrove and the Harecastle Tunnel. The pairing of nearly all the locks was done circa 1830 to speed the traffic.
