Sea-Dog 150105 Asymmetrical Snap w/Eye Insert - Stainless, 4"Designed to place more of the load on the stronger, non gate side which significantly increases the breaking strength over traditional rounded style snap hooks. The offset body style allows greater gate clearance, increasing the passage area into the snap. The eye insert provides a secure attachment to lines for use on harnesses, fishing lines, mooring buoy lines, etc. Formed 316 stainless steel.
