Abstract
An adjustable face-plate template adapted to be adjustably fitted and clamped to the longitudinal edge of a door to establish a predetermined-size recess for a face plate of a door latch or lock, wherein the template includes a first, adjustable, parallelogram structure defining a clamping device having a pair of clamping bars, and a second parallelogram structure defined by a pair of guide bars arranged to determine the width of the recess to be cut. Slidably mounted to one of the clamping bars is a pair of transverse guide bars adapted to be adjusted to establish the length of the recess to be cut. Both parallelogram structures are pivotally connected together.
