Common Concerns Answered
What if I can't find the exact mounting hardware?
While specific mounting hardware is often sold separately, Sea-Dog gas springs are designed to accept standard 10 mm ball mounts, providing broad compatibility with common hardware solutions available in marine supply stores.
Are there reports of these failing prematurely?
While occasional premature failures can occur with any mechanical component, Sea-Dog's use of high-quality materials like hard chromium plated shafts and bronze bushings, combined with their advanced multi-lobe seal, significantly reduces the likelihood compared to lower-grade alternatives.
Is the initial cost higher than generic options?
Yes, the premium materials and advanced seal technology in Sea-Dog gas springs result in a higher initial investment. However, this is offset by a significantly longer service life and superior performance, offering better long-term value and reliability for critical marine applications.
Frequently Asked Questions
What is the extended length of the Sea-Dog Gas Filled Lift Spring - 7-1/2" - 20#?
The product listing specifies a 7-1/2" length, which typically refers to the center-to-center distance of the mounting points in its compressed state or the overall stroke capability, not the full extended length. For precise extended length, consult the manufacturer's dimensional drawings if available, or measure the distance between mounting points when the hatch is fully open.
What is the compressed length of the Sea-Dog Gas Filled Lift Spring - 7-1/2" - 20#?
The 7-1/2" dimension typically represents the center-to-center length of the mounting points in the compressed state for this type of gas spring. The exact physical length of the cylinder itself will be slightly less to allow for mounting hardware clearance.
What is the force (in pounds) exerted by the Sea-Dog Gas Filled Lift Spring - 7-1/2" - 20#?
This Sea-Dog Gas Filled Lift Spring exerts a force of 20 lbs, which is the outward pressure it applies to assist in lifting and holding open a hatch or lid.
What type of end fittings does the Sea-Dog Gas Filled Lift Spring - 7-1/2" - 20# use?
This gas spring features durable polymer end fittings designed for secure attachment to compatible mounting hardware.
What is the warranty period for Sea-Dog Gas Springs?
Sea-Dog Gas Springs, including this model, are backed by a comprehensive 2-year warranty against manufacturing defects.
