Woodhaven 8650 Two Head Hardware Marking Jig Two Head Jig has two independently adjustable heads that can be spaced from a minimum of 1-3/8" on center to as far apart as needed for hardware out of the range of the 8630, 8640 & 8645 jigs. Marks up to 6-1/2 or 165mm from the top of a drawer or edge of a door. Includes a 16" One Track for doors and a 36" One Track for drawers, with longer One Tracks available. Easy 5 minute toolless assembly & track changeover. Reversible for right or left handed doors by simply flipping it over. Marks to the center of a 12" tall drawer. Jig lets you mark knob & handle locations for later drilling (uses the 8600 Marking Punch - order separately), which is easier then trying to hold the jig in position and drill the holes at the same time. All adjustments made with knobs. Optional 6505 or 6507 Self-Centering Drills can be used in place on the 8600 Marking Punch and are handy for face mounting hardware with wood screws. Pays for itself the first time you use it! Lifetime guarantee against defects in material or workmanship. Made in the USA!
