Muddycreek Tackle Small Cradle Rod Holder tubes are removable, which is great for storage purposes. The rod cradles are made with right-hand threads, so you can take them off quickly. An O-Ring on the threads absorbs vibration to keep the tube from loosening. Muddycreek states they make the rod holders out of heavier material than used by other manufacturers. A fully machined end makes a need for a rubber cap unnecessary. The options for these Muddycreek Small Cradle Rod Holders are a standard Single Mount Assembly and a standard Track Mount Assembly.
