A-frame - simple mod

I have a stainless steel A-Frame with 2 vertical legs on each side of the boat.

I want to add a horizontal length of stainless tube between the two verticals to mount light weight accessory.

Don't want to do any welding.

Need to work out a way to clamp together.

Any ideas?

Depending on diameters etc then perhaps something like these split clamps: Baseline Marine Products Ltd - Stainless Steel and Cast Range

90 Degrees T Joint, For 25mm Tube Clamp-ON

I see your comment about no welding which I understand for the boat but if you were happy to have a couple of flat plates welded on the end of the new tube you could U-bolt it in place.

I Googled A4 stainless handrail fittings to get the website above

I should have mentioned that the A-Frame is made from 2" stainless tube. Which discounts handrail fittings as they tend to be a lot smaller.

Get your 2 inch tube bent to suit have an internal pipe welded inside at each end at the fabricators slot inside your uprights and pop rivet through at the cardinal points

I've used the ones Poly sent the link for. They do 2" and 3" ones. Very easy to use and strong.
