1-1/4 in Sink Tailpiece Clamp-Socket Extension
A 100 mm extension for a bathroom-sink drain. It bridges the gap when a new vessel sink or faucet drain no longer reaches the old P-trap. The existing 1-1/4 in (31.75 mm OD) tailpiece drops 33 mm into a split socket and is locked with two M4x20 bolts and captive nuts. The 31.75 mm spigot below goes into the trap's slip nut and washer as usual.
