Adjustable hot limit safety stop allows you to limit the amount of hot allowed to mix with cold, to help prevent accidental scalding. Cartridge assures a lifetime of drip-free performance. Plaster guard is designed to protect valve during installation and serve as a mounting plate for thin-wall installations and the 2 piece design allows valve to be tested prior to trim installation. Pressure balancing valve cartridge maintains constant output temperature in response to changes in hot and cold supply pressure.
