(1) The T-connectors from Sage weren't reinforced and the cabling was cheap.

(2) Make sure the branch of the T-connector faces the wall behind the sink.

(3) You then push the cable connector on to one side of the T-connector and give the lock ring a twist.

(4) Unscrew the nut that connects the drain to the flange using an adjustable wrench if you are replacing the pop-up drain. Then remove the drain flange from the T-connector.

(5) If you can't unscrew the drain flange from the T-connector, use a reciprocating saw with a metal-cutting blade and cut the drain assembly away just above the T-connector.

(6) Different types of adapters are available for BNC connectors, including a T-connector, barrel connector, and terminator.

(7) Introduced in the paper are the structure and application of a newly developed marking gauge for drawing transitional line of round pipe T-connector.
