This is an uncut, never used, rail mount Navpod. This is the RMX4100 designed for a 4.5"x4.5" cut-out. Includes the parts to mount on 1" diameter rail but can also be mounted on 1.25" rail by purchasing a different nylon bushing (RMX-125). I believe these are available for around $10 from NavPod. Bought for our boat years ago but never installed. In excellent condition with some very light spotting on arm. Has two torx tamper-proof screws in back which I can remove before shipping. Four screws are needed to secure the face on. These enclosures are $400-$500 new. Please ask any questions, I'm happy to answer...
