I installed these to move around a computer desk. Very well designed. I did use larger screws than the screws included.

I used 2 sets of these (a total of 8 casters) to move my empty hot tub! It works like a charm. I like to keep my hot tub in one place most of the year, but then when the snow hits I like to move it under the deck. Luckily it is all on the same concrete patio. I used 8 of these casters secured to the bottom wood frame of the tub and can easily move the entire thing by myself. The best part is they can stay installed because the tub actually sits on the concrete when these are retracted.

At first I thought it would have been nice if the casters were assembled already, but in reality- you will have a heck of a time mounting them if everything is assembled.

I found it much smoother to install the mounting plate first, then assemble the caster and lever parts after. This ensured a solid mount with easy access to the screw holes and much better angles for the drill!

Only other tip would be to mount these about 1/16th higher than the specified height. When you get the package it has a template- I just didn't trim the edge of the template off (the side with the dashed line indicating to cut here) and it was the perfect height. Using the template as they describe will certainly work, but it leaves very little margin of error for the casters to retract fully. The extra 1/6th of an inch or so makes it so the wheels are definitely fully retracted and not supporting any weight at all.

Awesome little project that saved me a ton of effort and time over moving my hot tub the usual way. Well built for their weight rating.

These were exactly what I needed to move my 6 x 4 work table. My table has metal legs, so I didn't use the wood screws provided. Used self-tapping metal screws instead. Easy to install and easy to lower wheels to move the table around my shop. Would buy again.

I just installed these yesterday on my wife's gardening workbench. They work very well. Before buying them, I was concerned about how much effort/force it would take to bring the lever down that lifts each leg. But, after installing them, I found that it was reasonable. Engaging and disengaging the casters does not take that much effort.

Two notes that I think are worth mentioning:

(1) When you release a caster by lifting the lever up, you might want to consider simultaneously holding the table at that point while it lowers. Otherwise, for heavy items (my wife's workbench is one such item), it can slam down pretty quickly. May not be a problem for you -- it would depend on what you have on the bench.

(2) One of the videos recommends NOT trimming the bottom of the template card off before using it. (It's about 3/16" or so). I agree with this recommendation (I also did not trim it.) By trimming it you bring the mounting bracket closer to the floor which will result in the caster lifting the bench higher when it is engaged. This results in the items on the table temporarily being subjected to more of an angle as you engage each caster. Depending on the stability of the items on the table, this could result in some things tipping over.

Although I have only one day of experience, this appears to be a great product. Seems to be a better value than other retractable casters available - costs less and supports more weight. Also comes with two little wrenches to lock down the bolts and nuts included with the kit. All you need is a drill and a Phillips head screwdriver or power driver.

These took me about an hour to install. Others have done it faster but I'm a bit of a fussbudget -- needed to understand things before proceeding (a blessing and a curse). The screw fasters on the bottom of each mounting bracket end up being pretty close to the floor and therefore a little challenging to install (assuming you have to install with the table/bench in place without inverting it). I wouldn't call it a "snap" to install but it was indeed quite straightforward.

I would/will buy these again for other applications if they come up.

Great product for the money! Easy to install if you have some knowledge of how they work. Instructions overall are pretty lame. Some notes on the instructions.

Since your table is probably going to be upside down when you are installing these, make sure you pay attention to the orientation of the parts when building the devices. Seems like a silly statement but it is kinda important.

There are 8 total hinge bolts. 4 long, 4 shorter. Make sure you put them in the right places on the casters.
When using the template, they recommend you cut the bottom 3/16's off the edge. I recommend leaving it on and aligning the bottom of the template with the bottom of the leg of the table/workbench. This allows a little more positive contact with the ground when the casters are raised (table/workbench lowered).

These casters roll nicely on my concrete floor in my garage making it super easy to move my 24 x 48 inch workbench around where needed.

Because of the design of my workbench, the devices stick out an additional 6 inches from the legs. These are the smallest size and they stick out a pretty good bit. Keep this in mind when you are building/designing your bench and planning to use these casters.

Overall, a great design and product that I will incorporate again on future builds.
