The K-40 sits flat on the floor or countertop and also tips onto its back for easy access to sink drains and bathtubs full of water. It practically eliminates job site cleanup thanks to the patented guide hose two-way AUTOFEED® control.

Rated 5 out of 5 by from This product is portable, easy to operate My Grandfather sold wholesale plumbing supplies since the 50's, and he highly recommended his RIGID products. Recently, I had to snake a secondary sink located in a laundry room. Any plumber knows these types of cement sinks can have all kinds of problems. I pulled out his old K-40 and thought I would have a job ahead of me, but it came through without a hitch! If and when the RIGID tools he swore by ever give out, I'll gladly be back to buy from the newest generation of the same line that has served this plumber's family so well for so long! I'd buy any RIGID product with 'my eyes closed' ... that's the kind of confidence I have in their products!

Rated 5 out of 5 by from love because you never touch the cable hands always stay clean This drain snake is pretty light for the size and the features it has. The power is incredible for the size. The auto feed feature works great which results in a clean hands and work area less cleaning up after the job been completed. I also like the fact that the cord it comes with is pretty long no need for a extention cord must of the time. Another cool thing is for most drains you dont need to take the ptrap off you could snake a lavortory right threw the drain without removing the trap.

Rated 5 out of 5 by from The Best! The best drain cleaning tool out there! Our bathtub was clogged and we tried EVERYTHING. This was the one thing that unclogged it and it's been unclogged ever since. It drains better than it did when we bought the house!

Rated 5 out of 5 by from Better than a Pistol Rod I really like the fact I do not have to hold the machine with one hand while guiding the cable in to the drain. This machine has plenty of power to clear tubs, sinks, and even urinal drains.
