The hard accessory mount is designed to mount in the boat and allow easy removal of your chosen Miller Marine Products accessory. Most of our boating accessories are designed to accept one of two different mounts. The hard mount has two mounting screws with countersunk holes that accept a #8 screw. This mount is for use when not mounting to our patented rail system. If you have our rail system you may also want a few of these hard mounts to allow you to move an accessory such as a cup holder from the rail to another position in the boat where you have no rail, near the helm. The hard accessory mount is flat on the back and has a dovetail design to mate with the female dovetail pocket machined into the back of your chosen accessory. The hard mount measures approximately 3” long by 1.125” wide by .5” thick. This part is available in white or black plastic.
