There are three types of socket available for the Oxford Dipper pool lift. When correctly fitted the top of the 'A' and 'B' sockets will be 12mm below the floor level. The socket is supplied with a bkanking plu, seen below, to prevent ingress of water when the mast has been removed for storage. When fitted the top of the blanking plug is flush with the floor level and the metal 'key' can be unsrewed form the top of the plug to ensure that no tripping hazard exists.
The Oxford Dipper 'C' socket is surface mounted and stands proud of the floor by 150mm, therefore, no blanking plug is required.
