Patio roller no numbers found

A handy person from Florida, USA says:
Can you please help me identify these rollers so I can order them from you. I could not find any identifying numbers or writing on the units. If you need any additional information please don't hesitate to ask and I will get it to you. Thank you. Ron

Hi, Ron!

I recommend you start by having a look at our 81-289 and 81-046 rollers. Carefully review our dimensions and compare them with yours to see if one matches what you need.
