The Harwick sash stop adjuster is not your ordinary sash stop adjuster. It is stamped from .050" thickness brass. We made them thicker so that the screws will not pull through, and they look more substantial as well. Prongs maintain positioning. Slotted for maximum adjustability. Supplied with Phillips-head screws, easy to install with power tools. Available in unlacquered brass, dark bronze (US10B),and nickel-plated.
