The HoldRite No.115 and No.115-C (Copper-Bonded) are steel brackets designed to position water supply lines off the vent or waste pipe in chase walls. Supports 1/2'' through 2'' pipes both vertically and horizontally. Packaged with self-locking stainless steel band, screws, metal clamps, and self-adhesive isolating felt. Excellent for pre-fab applications. Supports piping prior to wall framing. Heat the pipe, not the bracket when soldering the No.115-C version.
