Rail's flat and horizontal? You don't need the adjustable version. This fixed-mount holder clamps onto a 25mm diameter rail and keeps your cup where you put it. 316 stainless steel, so saltwater and UV aren't going to chew through it. Simple, solid, no moving parts to work loose after a few seasons. If your rail isn't level or you need an angle adjustment, the MJE214 adjustable version handles that instead
