1.5-2.5mm

The smallest 200 Series band also carries the widest format choice in the line: 10mm and 15mm sleeves at 1,000-piece packs, plus a 30mm option at 500. That’s a meaningfully broader lineup than every other 200 Series size, which reflects how often this diameter range comes up – fine control and instrumentation wiring where cable OD varies enough between runs that a precision-fit 100 Series sleeve would need two or three separate part numbers to cover the same ground. One 1.5–2.5mm sleeve does the job across that spread, at the cost of a slightly looser tolerance than a single-diameter sleeve offers. The familiar dual-recess build carries over from the rest of Grafoplast’s slide-on range – one channel for the marking element, one for the wire – so tags can still be swapped without re-sleeving the cable. For stores that would rather stock one flexible size than three precise ones, this is usually the first 200 Series size reached for.
