A Simple Solution! Why drill two holes in your boat when one will do? The Mate Series Rod & Cup Holder combines both functions in one easy to install unit. When a fish strikes anglers can simply swap drink for rod and start reeling! These premium cast 316 stainless steel rod & cup holders feature a drink holder with a passthrough for a fishing rod. This single unit functions exactly like a rod holder and a cup holder combined. A simple right angle hole saw cut makes OEM installation and retrofits easy.
