This crescent-style lock uses a rotating lever to draw a compatible sliding window sash toward its keeper. Model E858 is shown in a golden finish with SS201 or iron hook components and a powder-coated or painted surface. Keeper alignment, lever clearance and mounting-hole positions must match the window profile.
Product Function and Construction
Turning the lever rotates the crescent section into the keeper and pulls the two window members together. The oval mounting base provides the fixing surface and sets the lever position relative to the meeting stiles.
Within Window Crescent Locks, base geometry and keeper position determine whether the sash closes evenly.
