Overlashing a large cable onto an existing aerial strand is the same job as a small one, only heavier: the cable has to be pulled along the span before the lasher goes to work, and a 2 in or 3 in cable dragged over the strand and the old lashing snags harder, scuffs deeper, and loads the pull more than a drop cable ever does. The Jonard Tools CR-300/4 is a four-pack of cable rollers sized for cables from 1 in to 3 in in diameter, fiber optic included, that snap over the strand so the cable rides on a roller instead of the steel. The rolling design keeps the cable from catching on the strand hardware, the existing bundle, or the lashing wire as it's pulled, the rollers are molded from durable nylon plastic for the rugged treatment aerial work hands out, and they snap on and off quickly, so a crew can space them down a span, make the pull, and collect them behind the lasher. Four rollers to a pack. For cables up to 1 in, the CR-150/6 is the smaller roller in a six-pack.

Features

• Cables from 1 in to 3 in (25.4 to 76.2 mm). Including fiber optic cable.
• Snaps over the strand. Quick to install and remove for overlash construction.
• Roller design. Helps prevent the cable from snagging and catching during the pull.
• Durable nylon plastic. Rugged design, built to last.
• Four rollers per pack. Enough to space along a span.

Where It Fits

It suits aerial construction crews overlashing high-count fiber, trunk coax, or armored cable onto an existing strand, telecom and cable contractors adding a large feeder or distribution cable to a span that already carries the drops, long-haul and middle-mile fiber builders running big loose-tube cable along existing pole lines, utility and broadband line crews who'd rather roll a heavy cable in than drag it, anyone who has pulled a 2 in cable over a strand and watched the sheath scuff at every pole, and a bucket truck that already carries the lasher, the strand grips, and the pulling grips. For cables up to 1 in, the CR-150/6 is the smaller roller; for the pulls that happen indoors, the CPF-215 Cable Funnel protects a drop-ceiling pull the same way.

Good to Know

The rollers go on the strand, not the cable: snap them over the messenger at intervals along the span, pull the new cable through them, and collect them as the lasher works down the span behind the pull. A large cable sags more between supports than a small one, so space the rollers closer than you would for a drop cable, and put one close to each pole where the pull changes direction, since that's where a cable catches. The 3 in limit is the cable diameter at the roller, so a cable with a splice case, a pulling grip, or a swivel on the end has to clear the roller too; check the grip before the pull rather than at the first roller, and a cable under 1 in belongs in the CR-150/6, where the roller is sized to keep it from wandering. A cable this size carries real pulling tension, so pull steadily within the cable's rated tension and bend radius, and stop and look if the pull suddenly loads up, because a roller that has rotated or a snag at a pole costs less to fix than a kinked fiber. Nylon shrugs off weather and won't mark a jacket, but it does wear, so retire a roller whose surface has gouged. Aerial work has its own rules on strand grounding, bonding, and clearance from power; the rollers are a pulling aid, not a substitute for any of that.
