Prime-line part F 2919 is a vinyl window sweep latch for use on single-hung and double-hung vertical sliding windows. This item includes a latch, fasteners, and easy-to-follow installation instructions. These bronze-colored latches are constructed of durable injected molded plastic which equips the window with long-lasting corrosion-resistant hardware, and they fit champion windows. The sweep latches are used nationwide, but they are typically found in homes and apartments in the midwest and northeast regions. Sash locks like these are used by many to replace damaged or missing locks and install them easily with a simple Phillips head screwdriver.
