NefishHeavy Duty Leveling Machine Casters 2200 LBS, Upgraded Ratchet Arm Design Leveling Retractable Castors Set of 4, Aluminum Base & Industrial Grade Rubber Workbench Caster for Industrial, Machine

This product appears to be heavy duty and time will tell whether it is durable. The construction includes a relatively thick gauge steel body to protect the internals; a small window on one side of the body allows access to the small ratchet arm that is used to raise and lower the rubber foot. 5/5 for ease of use.I used these castors for a portable workbench. The bench itself is about 200# and the castors are mounted to the bottom of 4x4 legs. The ratcheting rubber feet work as expected and are easy to use, providing a stable base for projects. The fact that you can ratchet each castor independently means that you can level the workbench on any reasonable surface. The only drawback I have noticed is that the ratchet arms can be kicked, or otherwise inadvertently be moved by accident, which can un-level the surface. If you are careful not to accidentally hit the ratchet arms, then this is a solid 5/5 for sturdiness; however, the fact there is no lock on these arms seems like a design flaw, so 4/5 for sturdiness.Finally, for installation I gave 4/5. This is in-part, my fault. Instead of installing these castors in a way that allowed me to use the provided hardware (i.e., machine bolts and nuts), I was using 5/16"x3" machine screws to mount them to the ends of the 4x4 legs of the bench. Since the dimensions of the 4x4 post is actually 3.5"x3.5", the 3.5"x3.5" face of the mounting plate on each castor completely covers the end of the post and leaves minimal space in each corner to sink the screw. I drilled pilot holes and was able to mount the castors using my machine screws. Since the screws were 3" long, it was difficult getting the heads to slide past the body of the castor while still driving straight into the mounting surface. I found that by swiveling the body so the ratchet cutout was facing the screw, the head clears earlier, and once the bolt head clears the body of the castor, it can be screwed in the rest of the way without obstruction. This would have been 5/5 if I had mounted it to an easier surface. It was actually difficult to get the screws far enough into the corner to match the bolt holes on the mounting plate without leading to a blowout on the 4x4 corners, and while managing the longer hardware... from an adaptability perspective it retains 4/5 on install. If you mount it as intended, it should be super easy to install.I would recommend this product, and I would use this product again.

So I just received these today so I have not set them up yet. This is a preliminary review so I will follow up later. My application is a very heavy sturdy wooden workbench. using 4x4s, 2x4s and a 30"x72"x1.75" butcher block top. I will have it in my basement and I want to have it stationary and put in a corner when not using then roll it out when I need to use it. The hardware that it came with will not be suitable for wood. I plan to use 5/16" lag bolts to attach to 4x4s (legs). These seem very sturdy and initial operations seem smooth and effortless. BEWARE you can walk the foot right out of the adjusting screw! I will put a mark at the limit of the stationary feet so this does not happen. But I wouldn't recommend having your hand or other appendage near them. Especially with a heavy object. I would also recommend just get it were it just contacts the floor and off the caster wheel. This should be plenty of room, just don't extend it all the way to the maximum height. I will post an update when I complete my project.

The media could not be loaded. Bearings held up superbly! Sleek appearance. Great size. Not bulky. Easy to secure. Rolls like a hockey puck on ice! Which helps aid In the easy access to the rear of the tanks. Helps with cleaning and checking on equipment. Quick pull out to get behind. extremely easy. Look at the amount of weight these bad boys are supporting. Fish give it a 5 star also 🐟🏆😊 5🌟 too!! Great material. The value we were looking for.

These leveling casters are great for their intended purpose of easy raising, moving, then leveling on an uneven surface. They are well made, easy to install, and do generally everything as advertised. That said, these feet are very vibration prone. I installed these feet on a 400lbs automotive fabrication workbench with a vice used to cut metal and due to the soft rubber leveling pad, they flex and move a ton under any sort of load or vibration. I regularly have items walk off of the table when cutting metal with my reciprocating saw with material in said vice. I will be putting these feet on a tool chest and replacing with a more sturdy option.

Pulled out of box. A pretty sturdy coaster. Rachet mechanism is stout. Look forward to installing on my shop work bench.

I have the ones that mount on the side (the removable ones). They bend if your table is somewhat heavy (say, 250 to 300 lbs loaded). These won't, plus they roll easily, without the bent wheel effect. Buy these for your table. Then build another and buy more. Great product.

I built a stand for my anvil and wanted to be able to move it out of the way. These level down and provide rock solid stability for my anvil, no wobbles, solid. The wheels are easy to extend and roll nicely when extended.

I do recommend these castes, they are well built, heavy duty and built to last. I used them to hold my Audio/Video rack.
