Ridgid 64298 – Frequently Asked Questions

1) Will the 64298 chain knocker work on my Ridgid FlexShaft machine?
It is built to attach to Ridgid FlexShaft power cleaning systems and is the K9-102 (also referenced K9-12) head. Match the head to the FlexShaft machine rated for 2 inch work; a 2 inch knocker on a larger-capacity FlexShaft will still only clean a 2 inch wall.
2) Is a chain knocker the right choice for a grease-clogged kitchen line, or do I need a cable machine with a cutter?
For grease, hair and other soft blockages, the looped-chain knocker is the tool: it spins inside the pipe and scours the wall all the way around rather than boring a hole through the stoppage the way a cable head does. That is why it gets used ahead of a camera inspection, since it leaves clean pipe wall to look at. The 64298 is specified for soft-walled pipe; hard scale and root intrusion call for a carbide-tipped penetrating chain knocker instead, which is part of the same FlexShaft accessory lineup.
3) Is the smooth chain knocker safe to run in PVC or thin-wall drain pipe?
Yes, the smooth chain configuration is the one specified for soft-walled pipe, which is exactly where you do not want an aggressive cutting head. It breaks up grease and hair against the wall without the carbide tips that the penetrating version carries.
4) What is the correct Ridgid part number to reorder this 2 inch FlexShaft chain knocker?
Order Ridgid part 64298. The head itself is designated K9-102 and appears in some Ridgid literature as K9-12, so both references point to the same 2 inch smooth chain knocker.
5) What other FlexShaft heads should I buy alongside the 2 inch chain knocker?
The Ridgid FlexShaft accessory range also covers nylon cleaning brushes, nylon/steel brushes, sandpaper blades for pipe rehab prep, carbide-tipped penetrating chain knockers, and ball/drop heads. A common van loadout pairs the smooth knocker for grease and hair with a brush for finish cleaning and a penetrating knocker for harder deposits.
6) How heavy is the Ridgid 64298 knocker, and does it add much to a service van kit?
It weighs 0.201 lb, so it is a pocket-sized spare. Shipped dimensions run 10 x 4 x 1.405 inches. Drain techs typically carry more than one head on the truck since the knocker is the wear item, not the shaft.
7) Where is the Ridgid K9-102 chain knocker made?
Finland. That matters for some government and institutional procurement files that require a stated country of origin on the submittal.
