At the center of our installation system is the HIT-45 modular clamp.  Using a revolutionary design, the HIT-45 clamp will work on aluminum, wooden or hollow metal doors.  HIT-45 has a grip range from 1 1/4" to over 2 1/4" without the use of special adapters or plates.  Clamping pressure is positive with the HIT-45 always being self centering by design.  The use of two internal locating studs assures that backset is calculated from door center, regardless of flat, beveled or radius doors.  The HIT-45 modular clamp will work with any router or drill template shown, with many more accessories developed for this unique modular design.
