TOTO Mounting member Long legs with take-out socket (with drain cock and stopcock)

It is a mounting leg for sites where the faucet mounting leg cannot be mounted on the pipe from the wall as it is.
It can also be used when a 130 mm long leg is set in the take-out socket and the hot and cold water pipes are taken out too far apart (for example, when changing a single faucet with different hot and cold water to a hot and cold water mixing faucet).
