Buffer Tube Ringer - up to 6 mm (BTR-6)

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

Getting into a buffer tube is the step where a careless blade ruins a dozen fibers at once, and the Jonard Tools BTR-6 is the tool that makes it routine. It rings buffer tubes from 1.2 mm to 6 mm in diameter with walls from 0.2 mm to 0.5 mm thick: squeeze the handles to open the jaws, drop the tube in, release, and rotate the tool around the tube, and the factory-fixed hardened steel blade scores the wall to a set depth without reaching the fibers inside. Flex the tube and the scored wall snaps clean. At half an ounce and under four inches long, with a hole for a tether, it lives in a pocket or on a lanyard and is there every time a closure or a tray needs a tube opened. It's backed by Jonard's lifetime warranty.

Features

• Rings buffer tubes from 1.2 mm to 6 mm. Covers the loose-tube sizes in distribution and backbone cable, with wall thicknesses from 0.2 mm to 0.5 mm.
• Squeeze, insert, release, rotate. The jaws open with a squeeze of the handles, close on the tube when you let go, and the tool turns around the tube to make the ring cut.
• Factory-fixed hardened steel blade. Set for a nick-free entry through the tube wall, with no depth adjustment to drift, and hardened for a long life.
• Light and small. 0.53 oz and 3.75 × 1.94 × 0.375 in, with a hole for tethering, so it goes everywhere and doesn't get dropped down a manhole.
• Lifetime warranty. Made for Life, and backed by Jonard's lifetime warranty.

Where It Fits

It suits splicing crews opening loose tubes at a closure, a tray, or a mid-span entry, FTTH and outside plant technicians breaking out fibers from distribution cable, data center and campus teams accessing backbone cable at enclosures and panels, anyone who has the mid-span and jacket tools but needs the one that opens the tube inside, and a tether-and-forget addition to a splicing kit, since it's the same tool in every Jonard fiber prep kit.

Good to Know

The tool scores the tube wall; it doesn't cut through it, and the fibers inside are protected because the blade depth is fixed to the wall thickness it's made for. Ring the tube, then flex it gently at the score line until the wall snaps, and slide the cut section off along the fibers; if the tube doesn't snap after a couple of flexes, make a second rotation rather than bending harder, since a sharp bend at the score can stress the fibers. Check that the tube is within the tool's range before you start, because a wall thicker than 0.5 mm won't score through and a tube thinner than 0.2 mm or smaller than 1.2 mm can let the blade reach the fibers. Make the ring cut a few inches back from where you'll need the fibers, so there's slack to work with, and a second ring further back if you need to slide off a long section. On gel-filled tubes, wipe the fibers after the tube is off; the gel remover and wipes are in the prep kits. The blade is fixed and hardened, and the tool is covered for life, but a blade that starts to drag rather than score is the sign to replace the tool rather than press harder.
