This worked perfectly once I made my own dolly with 2x6 boards. The dollys you can buy pre-made are too thin and not wide enough to make the rails sturdy. I do recommend this if you can use 2x6 boards.

Price was rt. Does what it should so far

We got these for our plant, and they are working terrifically! no complaints and they are able to handle quite a bit of weight.

Bought this on amazon, came the next day. LOVE IT!!! Use it to move a lot of heavy table tops around at work. Highly recommend it.

Exactly what I wanted and needed fast delivery great product

This Dolly converter was super easy to install on a 4 wheel furniture cart. Right after we installed it we used it to move a heavy mattress from one building to another. This made my job super easy and we plan to use this again very soon. Great for Moving!Dan Gales

Works well. Make sure it fits your dolly. I have several different 4 wheel dollies and the side boards vary in thickness.
