it's steel, 19/32" thick, 12_1/8" x 12_1/8" square and the groove
centres are 7/8" from the edge of the plate, and I found it in my loft.
Seems far too carefully made to be just a lump of steel plate.

Template for cutting roofing slates

It would be terribly heavy for use on a roof. Very dangerous.

Cut them at ground level then.


I do have a slate roof, but the slates are oblong rather than square,
seems something of an over kill for a slate template, it weighs 25lbs.
