The Crescent 1/2" x 100'/30 m NITE EYE™ Fiberglass Long Tape, part FE100B. It has a non-conductive fibreglass blade. Supplier specification: LONG TAPE 30M/100' FIBERGLASS NITE EYE.
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.
