Los pedí para una estructura de hamaca y son un poco más grande que los originales pero me funcionan muy bien apesar de tamaño

I have an older cast iron umbrella support anchor and it’s perfect. Had a few serious wind gust and she held steady as a rock.

Exactly what I was looking for. Knobs seem to work well and have not broken or spun off the shaft yet.I'm using this to attach a removable trolling motor mount I built for a canoe.

The size is perfect. The only issue was shipping time. Ordered 5/30 for delivery between June 6 - June 11. Finally got it on June 14.But the items are exactly as described and worked perfectly.
