Note: This replacement was developed to replace the discontinued G-U Tripact tongue version lock. It may not work as a replacement for other locks. Although the measurements for the two locks are nearly the same, the deadbolt and spring latch strike plates may need to be adjusted on the door jamb. In addition to relocating the strike(s), you may need to chisel out a small portion of the door jamb to accommodate the deadbolt and spring latch.
