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.

Concave post rails
Purchased 4 concave post rails to use in mounting 4 x 175 watt flexible solar panels to the Bimini frame on my 40.5 Hunter Legend. Panels will be supported by a frame of 7/8″ 316 stainless tubing joined by 90 deg corner fittings and T Fittings along the two interior rails all in 316 stainless. Used your drill guide Pro to mount the posts to the Bimini and the solar frame rails to the posts. Had to use a slightly longer bolt than one supplied with the posts to reach through the 7/8″ stainless tubing but all is secured and the panels are making power for both the 2 x 8D AGM house batteries and the AGM start battery. Thanks for the prompt service on my order delivery.

You are most welcome. We’re so glad to make things a little easier for you.
Drill Steady Pro
Great piece of kit, worked as described. Great for initial hole drilling and also as a pilot hole for a larger bit if a bigger hole is required.
Response from Gemini Marine Products
Yeah it’s a handy little thing, isn’t it? We’re glad you like it.
