morticer is positioned on the door edge to suit normal lock height and is
secured to the door by clamps. The lower clamp is fixed to the vertical bars

the clamps a cutter shaft in an aluminum housing assembly is traversed manually,
the distance governed by the spacing of the clamps. An electric hand-drill
powers the cutter.
