The HoldRite #114-C is a copper-bonded steel bracket with two slots for securely mounting upright to the carrier unit. The top end has a single 1-1/8" extruded hole for soldering 1" copper pipe, as well as supporting the water pipe for the flush valve above the floor. Adjust the flush valve 4-1/2" from the carrier center and 14" above the top fixture mounting bolt. This installation typically places the flush valve at 11-1/2" above the fixture, when soldering, heat the pipe, not the bracket.
