Mid Span Slit & Ring Tool, 1.2 mm-3.3 mm (MS-306)

Ships direct from the manufacturer. Please allow up to 10 business days, though it often ships sooner.

The smallest fiber cable, from a 1.2 mm buffer tube to a 3 mm drop, is the easiest to ruin on the way in, because there's almost nothing between the jacket and the glass. The Jonard Tools MS-306 is the mid-span slit and ring tool for exactly that range, 1.2 mm to 3.3 mm, with six precision slitting grooves on one side and six precision ring grooves on the other, each sized to a narrow band of cable diameter: 1.2 to 1.5, 1.5 to 1.8, 1.8 to 2.1, 2.1 to 2.5, 2.5 to 2.9, and 2.9 to 3.3 mm. Seat the cable in the groove that matches it and the blade depth is right for that jacket, with nothing to adjust; an indicator line on top of the tool shows where the blade sits, so the ring lands on your mark and the slit runs where you want it. It weighs under 2.5 oz, has a tethering hole, and takes the MS-306RB replacement blade set when the blades wear.

Features

• Slits and rings cable from 1.2 mm to 3.3 mm. Outer jackets and loose buffer tubes at the small end of the range, for mid-span entries and end preparation.
• Six slit grooves, six ring grooves. One side of the tool makes the longitudinal slit, the other makes the radial ring cut, with a sized groove for each cable on both sides.
• Groove sizes. 1.2 to 1.5 mm, 1.5 to 1.8 mm, 1.8 to 2.1 mm, 2.1 to 2.5 mm, 2.5 to 2.9 mm, and 2.9 to 3.3 mm.
• Blade indicator line. Shows the blade position on top of the tool for accurate slitting and ringing.
• Compact and tethered. Under 2.5 oz, with a tethering hole, for tight spaces and work on the go.
• Replaceable blades. Replacement blade set MS-306RB.

Where It Fits

It suits splicing crews opening loose buffer tubes in a closure or a tray, FTTH installers ringing and slitting 2 mm and 3 mm drop and cordage for splice-on and field-installable connectors, data center and enterprise technicians prepping simplex and duplex jacketed fiber at panels, anyone who has the larger mid-span tools and needs the bottom of the range covered without guessing a blade depth, and the fiber kits that carry it, since the MS-306 is the smallest tool in the mid-span set packed in Jonard's TK-106, TK-107, TK-107B, and TK-199B kits.

Good to Know

Measure the cable's outside diameter and pick the groove it falls in; on a cable this small, a groove one size too big leaves the jacket uncut and one size too small puts the blade into the buffer or the fiber, which is why the bands are narrow. For a mid-span entry, make the two ring cuts first with the ring side, using the indicator line to put the blade on your mark, then turn the tool over and slit between them with the slit side; on a buffer tube, ring it and flex the tube at the score until it snaps rather than cutting through, which keeps the blade off the fibers. Keep the tool square to the cable on the slit so the cut runs straight rather than spiraling, and let the groove set the depth rather than pressing harder. Fit the MS-306RB set when the blades start to drag or tear rather than cut; a dull blade on a 1.2 mm tube is a broken fiber. Tether the tool when working in a tray or over a manhole, since a tool this small disappears when dropped. Cable above 3.3 mm belongs to the next tools in the series: the MS-316 covers 2.9 to 6.8 mm, the MS-326 5 to 10 mm, the MS-426 5.8 to 12 mm, and the MS-526 9.8 to 18.2 mm.
