When my mat goes in the maker it just slides itself to make it work without any troubles. Now when i need the occasional tool, it rolls out without a fuss.
I put 4 wheels on it and as soon as i turned it over and the weight on wheels 2 wheels broke off. The weight on the wheels caused the wheels to break off.
The casters are a perfect fit and screw directly in as a replacement to the feet. Work perfectly with the uplift v2 standing desk at a fraction of the cost. Got this to add to my fully jarvis standing desk.
The wheels move freely and the lock is strong and sturdy. They work great on carpet, have a locking feature, and are a fraction of the cost of the ones sold directly by uplift desk.
