All aluminum parts anodized black, except red bush carrier; steel rods are ferro-blacked; register pins, fixing and clamping knobs are turned brass with knurled heads
Set the jig's rails at the desired inset from edge, fix them in position with thumbscrews on clamping rods and drill; guarantees holes will be exactly opposite each other and at equally spaced intervals
Twin-register pins have tapered tips to snugly fit drilled holes 3/16" to 3/8" (5mm to 10mm); positioned in rails, they fit into already-drilled holes, ensuring the holes will continue to be accurately spaced as jig is moved; accurately chain drill an entire upright without detailed measuring
24" rails each have 20 holes drilled at 1" intervals and space for chip clearance is provided; bush carrier registers perfectly in each hole and is easily moved along rails
Holes are drilled at exactly 90° to the surface because drill bushings are 13/16" long
Regular-length clamp rods are included for material up to 12" wide; long rods are available for material up to 24" wide and extra-long rods for work up to 36" wide
7mm sleeve-setting punch with hardwood handle included to set most common European support/sleeve combinations without damaging sleeve or work
11 bushings included: sizes 5, 6, 6.75, 7, 7.5, 8 (5/16") and 9mm, 7/32", 1/4", 3/8" and a soft bushing
