SPACECARE Workbench Casters, Heavy Duty Retractable, 800Lbs Capacity, Set of 4, Steel Construction, Swivel, Retractable Height Adjustment, 360-Degree Swivel

Very impressed with this product, just what i needed.

Highly recommended, these castors are great, ignore those comments about poor instructions, you don't need them as they are easy to install. My bench is very heavy and they work very well, makes moving it around the floor a breeze.

These casters work as expected. I purchased them with the mounting plates from Powertec. I can’t comment on whether this combo can hold 800 lbs, my bench does not weight that much. I don’t know what it weighs but it is perhaps 350 lbs. The casters and the mounting plates are very convenient as a package. A word of warning, any casters like this will twist your bench as only one leg can be lifted at a time. That said, some people have attached a bar between 2 casters so both can be raised or lowered together. I have not done that but like the idea.

Attaches easily to the side of bench leg. Lifts one cm off flooor, rolls well. Perfect.

Happy with my purchase. The casters were easy to install. The "instructions" were simply a diagram with the dimensions of the caster bracket and included no measurements for mounting them on a workbench leg. It would of been nice to have the exact measurement to be able to mount them. I ended up mounting the base of the bracket 44mm up from the floor which gave me a 10mm clearance , this suits my needs. At this time (one month after installing) I would happily recommend them to others. They are only let down by the lack of mounting instructions.

The included temple takes away the need to measure anything. Easy to install even though I hate Philips head screws. These casters makes things super easy to make the bench mobile.
