Sea Sucker is a Florida-based designer, manufacturer, wholesaler and retailer of kick-ass marine accessories, bike racks and board racks for cars, and small electronics mounts for holding iPads, iPhones and similar gadgets.
Their products are built around a mount with an integrated pump that creates a vacuum. The 4.5" model is rated to pull up to 120 pounds, while the 6 inch model is rated to pull up to 210 pounds.
Attaching to a surface, including the textured surfaces common on kayaks, is as simple as pumping the plunger in the mount. In addition to creating a vacuum the plunger acts like a check valve, so when there is enough vacuum pressure in the mount, the plunger is depressed and the orange band is no longer visible.
On top of the mounts are two slotted holes for back-plating accessories or mounting hardware and one center stainless steel insert for mounting anything with a standard ¼-20 machine screw. All metal parts are high grade stainless steel, even the springs inside our pump, for extra durability in the saltwater environment. The options are endless for customizing your fishing kayak. Sea Sucker also sells a variety of pre-configured mounts.
