my homemade arch in progress, 20" x 54"

[RigaudBeach]

They are not threaded into the support bracket. I made them rather easily. In my case I bought a 3 foot length of 3/4 inch threaded rod, 6 x 3/4 inch washers, 6 x 3/4 inch bolts and 2 hockey pucks.

I originally wanted to buy them but couldn't find any anywhere at a reasonable price. These came in under 20$ and about 15-20 minutes worth of work.

here is where I got the idea
