Our heavier weight dryer vent and pellet vent sweeping rods, priced per rod. Order the number needed for your use. Some folks prefer these stiffer rods all the time but for most professionals their use is limited to longer vents where the stiffness allows the torque of the drill to be delivered to the tool without twisting up. Picture shows all the dryer vent rod choices we offer, FYI. Not for use in chimneys as the aluminum fittings wear quickly on steel chimney materials.
We call these "commercial" rods as they are stiff enough to spin whips and brushes in larger dryer vents up to 8-10" diameter. For vents larger than this move up to the new #7163 7/16" Slick rods.
This nylon material is workable down to 10 degrees F. For colder climates use our 3803S Slick rods. Made by us in the USA. See video below to see our patented ButtonLok fittings click together, first and still best on the market!
HOT TIP: When using do NOT stroke back and forth simply advance the drill and rods pushing the brush (or if heavy build up the clog buster whip, our 2730V) forward into the vent. Add a rod and only move forward again and repeat until the other end of vent is reached. Ideally pop out to "free air" beyond the termination. Those who state "I have to stroke back and forth to bring back the loosened lint" are not using enough vacuum to evacuate the loosened lint (ROVAC recommended from laundry room side). Or, if they are using the blow of the dryer (or better yet a leaf blower), they are getting a lesson in why the vacuum method is often better. In such cases, minimal air flow to move the lint cannot be easily achieved. The solution then is to use the clog buster to drill through the lint piles to get air flow for the evacuation of loosened lint. The use of the blue PS4 brush after the clog buster will remove the last traces of lint.
