How do you replace the casters? I have a broken one, and tried using allen wrenches and I can't get them to loosen.


Thank you for contacting Contractors Direct.

If you use the wrong size allen wrench, you risk stripping the bolt. We will contact the manufacturer to obtain the correct allen key size.

Which pieces are included in this ? as it is in the picture ?

This item is the full Racatac with 3" casters and this package includes the chest support.

IDoes it come with 2 inch casters ? so it will be closer to the floor.

The caster size doesn't change the height to the floor. They do offer a 2 inch caster option. The caster size just helps in moving more smoothly over a rougher surface.

What length chest support post is included?

The steel post included for the chest support measures 12".

Does the 3" casters roll smoother than 2" or does it matter?

Both size casters will roll just as smooth as the other. The only difference would be the height. A customer would purchase the 3" caster if they would like to be higher off the ground.

I have a creeper already however as I live in Florida and now need to use my equipment I find the 3" wheels are disentrigating. I would like to find out how I can purchase new wheels.

We sell 3" replacement casters for the Rac-A-Tac. They are under SKU: R10063.

No More Back Attack

by -

Working on floors and any activity which requires kneeling or bending. I even use it to wash my dogs in the bathtub. No more lower back aches or sore knees and feet. Two men I know have and use them and it makes a huge difference especially when you are not 18 years old anymore.

This is a great item, it saved my knees and back while refinishing our hardwood floors. I have to admit is not easy to get into or out of, for this almost 60 year old. But once you get the hang of it, it does as promised.

Racatac w/chest rest---Excellent product, highly recommended- 25 out of 5 stars


I bought this to use to install a fairly large area of porcelin tile. I just completed the project and can't say enough good about this product.

I would have paid $2200 vs $227 knowing now how it worked for me. I finished the project in about 1/4 the time i would have having not had the racatac. Also the chest support was extremlely helpful. It also was removed when reaching out longer distances. Also, the 3" casters worked great for my size 14 feet.

racatac with chest support


This has been one of the best tools I have ever bought. If you do flooring of any kind this is for you. It helps to keep your back from getting so tired. It's a quality product. Worth every dollar.

Great tool

by -

Awesome for open areas. Took a while for me to get used to but once I got the adjustment height of the seat and chest support locked in its pretty comfortable to be on all day. Knee pads are a little stiff but switched out for a little softer ones and I can really move on this thing.. ..troweling, skim coating, glueing this thing is legit. Rolls pretty good on Comercial carpet which I was skeptical..

Bent the tip stop the first day granted I am 250 lbs but would suggest using a steal stopper instead of aluminum.. guess they were trying to keep the weight down.. changed that as well not a big deal..

All and all good buy

Great product!


Awesome product. I'm tiling a 1500 sq ft home and this is a God send. Really makes it easy on the knees

Easy to use and comfortable


I spent 6 hours a day for the last week installing rubber base. I don't think I could have done it without this. It rolled easily on the carpet and all my tools were handy. It's a must have for flooring/base installs.

Excellent tool


One of the best tools I have purchased. It makes working on your knees almost effortless.

Very satisfied


Awesome exactly what I was looking for received in a timely manner at a great price

Great Customer Service


I was very pleased with customer service when ordering this item. I was given a delivery date but I received the item even sooner. Excellent service and we love the RAC-A-TAC.

Awesome product


Bought this for my son. He does body work and says this is awesome! He is more efficient.
