Concave fork and post rail mounts
Exactly what you needed

Elegant design
Our concave fork and post rail mounts were developed to install solar panels on dodgers and bimini tops, where quick release pins and unusual alignment angles are the norm, but they can do much more.
This is flexible hardware that also enables you to locate spreader bars on the underside of bimini top roofs and dodgers, hiding the tensioning devices and doubling up as overhead grab rails. You can use them to attach grab rails outside dodgers, or to fix accessories like radar antenna to tubing anywhere on your boat. While you may find other fork mounts on the market, our forks are fixed at 90 degrees to others, allowing you to attach perpendicular to the underlying rail.

Easy Install, functional hardware
I recently purchased 4 Concave fork mounts to install a new Solar panel. The mounts installed easily and are highly functional. The finish installation was quick and professional!

Solar mount
Perfect solution to mount a solar panel on the Bimini.
Response from Gemini Marine Products
Thank you! We do like that word “perfect”…
Exactly as described
Able to install both grab rails in less than 30 minutes once I measured and cut the stainless bars to size, which I used a stainless tubing cutter to do. Making an exact measurement was challenging since the tube was too long for the grab rail but I got close enough to produce a secure grab rail.
Response from Gemini Marine Products
Excellent news and congratulations! We’re so glad you like it.
Almost Perfect
Great Product, good quality. I just wish the hex screw came in from the other side. It has an embedded hex nut so you can’t change the arrangement. If you’re adding this to an existing Dodger it’s just hard to tighten it without removing the Dodger. That’s the only reason for not giving it a 5 star rating.
Response from Gemini Marine Products
That nut absolutely DOES come out, precisely so you can switch the hex cap screw around. Go on, give it a go. We guess that makes it perfect…?
Solar panel mount
Outstanding product. We mounted our solar panels to Bimini frame and also created strapless Bimini and dodger. This is our second order and we are extremely pleased with the products and service
Response from Gemini Marine Products
It was lovely to see your name come up again – we’re so glad these mounts did the trick.
