Halsey Taylor has published a new Rough-In Guide for its Voyager line of water coolers. The template was designed to make the roughing-in process as quick and easy as possible for plumbing contractors. Molded from sturdy sintra material, the Voyager Rough-In Guide provides the installer with the recommended locations for the waste outlet, water supply and electrical supply in seconds. The 32-3/4" length also allows for the exact location of the hangar bracket. Halsey Taylor.
