Whether it’s a deck hatch, cooler lid, tackle station, or dock box, this 12-inch hatch support spring helps you work hands-free and stay organized on the water. Open the lid and the spring snaps straight to hold it securely; give it a quick deflection to close just as easily. It’s an easy upgrade that adds safety and convenience in tight spaces.

Engineered for marine duty, the stainless steel spring resists rust and pitting in freshwater or saltwater environments. Molded nylon mounting ends add strength, damp vibration, and won’t mar finished surfaces, so the support stays solid season after season. Dimensions are 12 inches long by 5/8 inch diameter, matched to a 20 lb lid capacity for dependable everyday use.

Installation is straightforward: the molded ends mount with four countersunk screws (not included), and the low-profile design tucks neatly alongside lids and hatches. No gas struts to wear out—just a proven mechanical spring that works every time you open the lid.

Built in the USA with globally sourced components, this support reflects the reliability boaters expect on American waters. Outfit your rig with hardware that stands up to long weekends, rough runs, and countless open-and-close cycles while supporting American jobs and know-how.
