Mountain Plumbing mt30-18/pn Ceiling Shower Arm 18 in

Product Description

The MOUNTAIN PLUMBING mt30-18/pn is a solid brass ceiling-mount shower arm designed for use in residential shower installations. Measuring 18 inches in drop length, this arm connects to standard 1/2 inch NPT supply lines and terminates where the showerhead attaches. A 2-7/16 inch decorative round brass escutcheon is included to cover the ceiling penetration for a clean finished appearance. Licensed plumbers and experienced tile contractors install this type of fixture during new construction or shower remodel work. The solid brass construction supports long service life in wet environments.

This ceiling-drop arm is suited for residential bathroom shower systems where a rain-style or overhead showerhead installation is desired. The 18-inch drop brings the connection point down from the ceiling to an appropriate height for pairing with a compatible showerhead. Its round profile and included escutcheon make it a fit for modern and minimalist shower enclosures. No specific compatible showerhead model numbers are stated in the product data, but the standard 1/2 inch NPT thread accommodates most residential showerheads.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply to the shower system before beginning any work. Apply thread sealant tape to all NPT threaded connections before assembly. Do not overtighten the arm at the ceiling fitting, as solid brass threads can be damaged by excessive torque applied without a backing wrench.
