HOLKIE Leveling Castor Wheels Set of 4 Heavy Duty Retractable Casters, M12 and 1/2" Stem Size, Total Capacity 1000KG, Adjustable Castors with Ratchet Handle for Workbench, Furniture, Machine

Brilliant casters! Would recommend!

These will be going onto a small bench for doing some crafting and although they might be slightky overkill on the weight and spec, I needed something that is completely adjustable so I can make sure it's completely level for doing resin work on and then as each foot is adjustable, I can also tilt both back legs up to create a tilting bench for other work.These feel really heavy duty and well made and worth the price which is around £60 at the time of my review. Especially as the casters also swivel and adjust.

The only issue with this item is the lack of full information with regard to the fixings.What it SHOULD say is:"The fixing is a 14mm screw thread, and the units come with 12mm and 1/2 (Whitworth or UNC?) adaptor studs"I had to use longer fixings and if i'd known that the fixing in the caster was NOT 12mm I could have gone and got the correct fixings in advance,However this is minor gripe on what is an excellent product

These are solid and well made. I bought them to attach to a lathe, to make it easier to move out of the way when it’s not being used. They worked well for this, but increased the amount of vibration in the lathe when it was being used so I had to remove them again. So, a good idea, decent quality product but it wasn’t a good soloution for my problem.

I fitted these to a very heavy wooden workbench in my workshop. It would have been easier were the fixtures a square plate. A hole had to be drilled through the lower legs and these casters secured through the hole with a nut. Once in place though it makes shifting the bench a doddle.It's easy to raise and lower the entire bench with the help of a screwdriver for leverage. Honestly, I can still raise the bench using just my fingers, but it's far easier with a little help.In the lower position it's a very sturdy base for heavier work. In its raised position and on the wheels the bench is easy to relocate, which frees up limited workspace for exactly what you need at that time.Very happy to have the chance to use these. They've transformed a limited workspace to be much more configurable to multiple needs.They're hefty things and I can't really see visually any potential weak points. The bearings are smooth and make pivoting seamless.Nice things. I might buy some more for a server cabinet case that has suffered with lacklustre casters since delivery.
