40 Series Precision Jigs

About 40 Series Precision Jigs

Precision drilling and alignment jigs for 40 series aluminum extrusion such as 4040 and 4080. Offset drilling jigs put one, two or three holes at fixed distances from the edge of the extrusion, for example 20mm, 20 and 60mm, or 14, 54 and 94mm, so every blind joint lands in the same place. Freehand drilling jigs drill an accurate hole anywhere along the extrusion, and perpendicular alignment jigs hold two pieces flush and square while the joint is tightened.

Blind joints reduce the need for external brackets and give cleaner joinery without giving up strength. See one in use in the 40 series drilling jigs video. Running cables inside the frame? See the Concealed Wiring Jigs.
