I would not recommend using scaffolding with wheels on grass or gravel without plywood or something similar under the wheels. Best bet would be take the wheels off and set the scaffolding on 2" lumber.
Hi Oscar. On the website or app it will give you shipping times and shipping options. For these casters the app tells me they can be shipped to arrive at my house by June fifth. I am only given one shipping option, but I live in the sticks so I'd expect your shipping options and speed to be a little better. On the app the shipping timeframe is on the add-to-cart button.
I measured with a tape measure and got either 1 1/4 or 1 5/16 in. I see in your message that you need 1 1/4 in. Is that an absolute?
