💡 How do you calculate proper preload for heat tempered extension springs on marine davits?

Proper mounting prevents premature coil fatigue during rough sea conditions. - Match the resting length to your span so the metal stays within safe stress limits - Thread the dual hooked ends straight through reinforced brackets avoiding sharp bends - Coat the exterior lightly with waterproof grease to stop salt buildup and rust formation - Swap out worn units quickly since the standard sizing fits most recreational rigs. ✝️
