The Crescent 1/2" x 10' L600 Series Power Tape Measure, part L610-02. Supplier specification: POWER TAPE 10' L600.
The specification professionals compare is standout — how far the blade extends unsupported before it folds. A wider blade stands out further, which is why a 1-3/16" blade reaches across an opening a 1" blade cannot. Length matters less than most buyers expect; standout and a legible blade matter more. Open-reel fibreglass tapes are non-conductive and do not rust, which is why they are used for long runs and around electrical work.
