I had to buy a bunch of casters for a couple of large garage tool drawer chests I was making for the garage, on top of which some heavy tools were going to be (i.e. 100kg drum sander), so I needed something that could take the load. Equivalent casters at the big green store were running at close to AUD20/unit, so these at AUD7.50 are an absolute steal and I would say as good as those I would buy from the other store. I HIGHLY recommend these.
