I LOVE CASTERS! How to love videos - I love it 100 times more! I ordered these before completing my workbench frame and after a very thorough review/comparison by an Amazon customer who compared them to the Rockwell version. I had a couple of port freight reels waiting but once they arrived and I checked the quality I knew they would kick ass without hesitation I sent the HF reels back and installed them a month later. To be honest, I've raised and lowered my workbench about a dozen times. I sat and admired the coolness of these things more than I care to admit. Although my woodworking skills are still very beginner, I feel like a pro. I've placed them on the inside of my racks as installing my WB will store nested carts underneath so these have been easy to move so far. Take this into account when installing. I also added some thin fabric to the bottom of the legs to prevent damaging the posts. This kit is packaged well, good weight and strength, installation was easier than any of my other reels - even easier than the cheap ones that fit plastic carts which are obviously basic but you get my meaning. In short these reels are awesome, the price is awesome and I would happily put them on anything. Some of the other customer photos show the wheels tilted - mine don't look like it, and mine don't rise more than an inch, which is what I wanted. If you discuss these STOPs, get these videos now! You will not be disappointed!
