Getting through corrugated armor without touching the fibers underneath is one of the least forgiving jobs in cable prep.
The Ripley Miller ACS Armored Cable Slitter (37880) is the professional-grade answer: it slits the outer polyethylene jacket and the corrugated copper, steel, or aluminum armor layer in a single controlled pass, on fiber feeder, central tube, and stranded loose tube cables — plus jacket and shield slitting on non-fiber armored cables.
A guide wheel stabilizes the tool on the cable so the cut tracks straight, and the precision-adjustable blade depth (up to 0.22" / 5.5 mm) lets you set the cut to the armor and no deeper, protecting the tube bundle inside.
The blade rotates 90° with a simple lever, so the same tool performs both longitudinal slits for mid-span access and circumferential ring cuts for end prep — no tool swap in the splice pit.
The ACS accommodates cable outside diameters from 0.315" to 1.125" (8 mm to 28.6 mm), covering the bulk of OSP feeder and distribution plant.
Made in the USA, with replacement blades available separately so the tool stays in service for years.
