Coldene Castors Ltd - Heavy Duty Castor Pack Of 4 Braked Bolt Hole Caster Wheel - (50mm / 2")

I used these on a wooden bench which I use for light duty assembly tasks.M8 bolts fit in the castor holes. The holes are not threaded.I had to remove the wheels to fit longer bolts but that was not difficult.The locking mechanism on the castors works well enough.I wouldn't use these on a workbench but they are fine for a trolley.Overall they are good value.

Used to make a heavy racing cockpit mobile. Works a treat.

They are just the job. Thankyou

good
