Great concept..a little more work
I bought a few of these for the first time. I thought it would save time, space and effort in locking together a few of the 2' wheels. At best they were ok. It could have been better if I would have done more work and realized which bolts I had on-hand and not.. We had to get creative with our screws and washers to get these to work. So far so good.
The threads are no issues even after many installations. The screw on the opposite side of the D cut transfers lots of torque. I wish it was steel though because the bore started to wear out
These nubs require threading and are easily broken. When changing the wheels on our tile runner, we had to purchase new nubs because at least half of them broke. From the AndyMark Support Team: We're sorry to hear that the Nubs were breaking. This sounds like an odd situation.
