Sea-Dog Line 321650-1 Stainless Steel Hatch Spring with Overextension Protection

The Sea-Dog Line 321650-1 is a heavy-duty stainless steel hatch spring designed for marine applications requiring reliable hatch support and controlled motion. Constructed from corrosion-resistant stainless steel, this spring is engineered to withstand harsh saltwater environments while providing smooth, consistent operation.

Key Features:

• Internal wire safety mechanism prevents overextension during normal use
• Corrosion-resistant stainless steel construction for marine durability
• Designed for controlled hatch opening and closing applications
• Ideal for cabin hatches, storage compartments, and access panels

Important Application Note: This spring is not recommended for applications where the hatch will scoop wind while the vessel is underway, as this may cause overextension beyond the internal wire's protective capacity. Best suited for hatches in protected positions or those that remain closed during operation.

The Sea-Dog Line 321650-1 provides a reliable solution for marine hatch support where controlled movement and corrosion resistance are essential.
