Built for Marine Environments
This SpringLift gas spring is designed for demanding boating conditions and is made for use in wet, humid, and saltwater environments. Attwood gas springs are made with environmentally responsible, water-safe grade oil and are tested for salt-spray resistance and long service life.

The blade-style end fitting is designed for secure attachment in compatible marine lift-support installations. Mounting brackets are sold separately, so existing hardware should be checked for compatibility before installation.
