Ridgid 64288 – Frequently Asked Questions

1) What pipe size is the Ridgid K9-102 chain knocker made for?
The K9-102 is a 2 inch (50 mm) knocker, so it is matched to 2 inch drain lines. Running it in larger pipe means the chains no longer reach the wall and you lose the wall-to-wall scraping action that clears scale and grease, so size the head to the line you are cleaning.
2) Will the K9-102 knocker fit a Ridgid FlexShaft drain cleaning machine?
Yes. The K9-102 is part of the Ridgid FlexShaft accessory line and attaches to Ridgid FlexShaft machines. It is a head only, so you need the FlexShaft machine and its cable to run it.
3) Is the K9-102 the same thing as a Ridgid K9-12 knocker?
Same head. Ridgid references this 2 inch carbide tip chain knocker as both K9-102 and K9-12, and it is ordered as part number 64288. If a parts list in your shop calls out K9-12, this is the item.
4) Can I run this carbide chain knocker in PVC or other thin-walled pipe?
It is specified for hard-walled pipe types. The 2-chain carbide head delivers aggressive wall-to-wall contact for scale, light roots and grease in hard-walled lines, which is what it was built around. For soft or thin-walled plastic where you do not want the wall cut, pick a less aggressive smooth-head FlexShaft knocker in the same 2 inch size.
5) Should I use a carbide tip penetrating knocker or a smooth chain knocker in a 2 inch line?
Go carbide-tipped when the line is fully blocked. The penetrating carbide tip on the K9-102 is built to cut into compacted grease, hair and other soft obstructions that a standard smooth knocker cannot open. Once the line is flowing, the 2-chain head scrapes the wall for scale and light roots. Smooth heads are the choice where you are only descaling and want less aggressive contact with the pipe wall.
6) What blockages will the K9-102 actually clear?
Grease, hair and other soft obstructions in a fully blocked line, plus scale and light roots once it is through. Typical work is residential and commercial sewer and drain maintenance in 2 inch hard-walled lines. Heavy root masses and solid intrusions are not what this head is for.
7) Is the Ridgid 64288 a complete tool or just a replacement head?
Replacement head only. The 64288 is a drain cleaning accessory, a 2 inch carbide tip knocker weighing 0.223 lb, that mounts to a FlexShaft machine's cable. No machine, cable or drum is included.
8) How many chains does the Ridgid 64288 knocker have, and why does that matter in small pipe?
Two chains. In 2 inch pipe a 2-chain head keeps the contact consistent around the full circumference while leaving enough clearance to pass debris, which is why Ridgid pairs the 2-chain layout with the small sizes rather than the heavier multi-chain heads used in larger line.
9) Where is the Ridgid K9-102 FlexShaft knocker made?
Finland. Ridgid manufactures this 2 inch carbide tip chain knocker there, which matters on public and institutional jobs where country of origin has to be documented on the submittal.
