Attwood Stainless Steel Gas Spring, 10 x 7 Inch, 20 lb Force, Boat Hatch Adjuster ST30-20-5

The Attwood ST30-20-5 is a stainless steel gas spring built to hold boat hatches, lids, and access panels open safely and smoothly. Gas springs like this one use a sealed, pressurized cylinder to counterbalance the weight of a hinged hatch, letting it lift with light effort and stay open on its own instead of slamming shut or requiring a separate prop rod. Because the housing and rod are stainless steel, this gas spring is built to hold up in the wet, salt-exposed conditions typical of a marine hatch, locker lid, or storage compartment application.

This unit measures 10 x 7 inches and is rated for 20 lb of extend force, and it is sold under Attwood part number ST30-20-5. It is a compact, lightweight component at 0.3885 pounds, making it easy to handle during installation or replacement on a boat hatch, engine hatch, or storage lid where a controlled, self-supporting lift is needed.
