AS-3 Adjustable Square

The small size of the AS-3 Adjustable Try Square does many things very well. Like the AS-14,
the inside rule is precisely aligned with the inside face of the
handle, and the outside rule is accurately registered with the back of
the handle. The blade measures 3" on the outside and 2" on the inside
rule. It is perhaps the finest tool yet invented for setting router bit
depths. Set it on your router base, spin the bit to the height of your
choice indicated on the rule and off you go. Another terrific function
is the ability o get into confined spaces. Small drawers, scaled work,
box making, model making, and joint work are but just a sampling of the
applications for this new and exciting square.
