I’ve Always Noticed A Black Diamond On My Tape Measurer, But Had No Idea Why Until Now


“The diamonds, many call them “truss markings”. But in Canada, the are joist markings. The 3/4 inch floor sheeting is rated to a maximum of 24inch span. Or, 4 spaces (5 joists) for every sheet. But to shrink it up so it has more tolerance and not at it’s “maximum” They use a spacing that is smaller than 24in, but bigger that the old standard, 16inch (6 spaces/7 joists).”
