J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Pushpit-quick question

I'm on my way to buy some clamps for speakers that will clamp to pushpit. Clamp sizes are 7/8 inch or 1 inch. Anyone know which will work? Thanks

All rails are 1"

Funny story. I need clamps to mount rear stern rail seats I'm making. I ordered two pair from the "HELM" website. The model number is "HELM FHC-12". I never received them. I called the company and phone Buber was disconnected. I checked website and it's shut down. I'm out $35. On another note. Downwindmarine.com sells them for $12.35 a pair. They're on backorder which means I probably won't get them.
