2468 Simple Underpinner Head

V Nails cannot be hammered in - they must be inserted with suitable tools

The Simple Underpinning Head fits into almost any drill stand with a 43mm opening. Mitred mouldings need to be clamped firmly together, using a band clamp or corner clamp.

A V-Nail of suitable length (max 2/3 the height of the moulding) is placed vertically on the end of the magnetic tip, sharp edge down. The point of the V should be on the moulding join line. Pull the lever steadily down to squeeze in the wedge.

You'll find it helpful to make up three blocks of suitable height to support the other three corners while joining a frame.

Designed for use with softer wood mouldings only.
