Sea-Dog Gas Filled Lift Spring, 60 lb, 20 Inch Extended Length for Marine and RV

The Sea-Dog Gas Filled Lift Spring (321486-1) is a 60 lb rated gas spring built to marine OE standards for supporting hatches, doors, and lids in the open position. It extends to 20 inches and compresses to 12 inches, giving 8-1/8 inches of stroke, and is fitted with a 15 mm ball socket end that accepts a 10 mm ball. The shaft is hard chromium plated and rides in bronze bushings, while the end fittings are polymer, a combination designed for long service life and reliable performance in wet, corrosive marine environments. A unique multi-lobe seal design is used to extend seal life compared to standard gas spring seals.

This lift spring is rated for both marine and RV use, and is also suited to engine or access hatches, doors, tool boxes, golf carts, canopies, seating, truck caps, and utility boxes. It is backed by a 2-year warranty. Each unit is sold individually (1 each) and does not include mounting hardware beyond the fitting itself.
