Aluminium Box Rule 5 metre length with a cross section of 4x2 inch (100x50mm). A heavy guage rule thats very very long! Idea as a straight edge, milled to within a tiny percentage of true. Ideal to be easily cut down and used as a bench guide for run mould manufacture or indeed as a floor laying rule, this is a very heavy duty piece of kit.

Easy to cut down as its just aluminium to any length you might need. Most of our customers shorten these to a 3 metre length and a 2 metre length.
