Attwood Marine Stainless Steel Snap Hook, 5/16 in x 3-1/8 in, 575 lb Safe Load

Overview

The Attwood Marine 12415L3 is a stainless steel marine carabiner with a spring-loaded closure for clip-on connections around the boat that need to open and close without tools. It measures 3-1/8 inches long with a 5/16 inch ring diameter, so it fits many utility attachment points without taking up much room in the cockpit, locker, or at the dock.

With a 575 lb maximum safe load, it works well for everyday onboard tasks such as securing utility lines, hanging fenders or buckets, and clipping portable gear that gets moved on and off the boat. It is not intended for lifting or for any job where personal safety depends on the hook.

Key features

• Stainless steel body with a spring-loaded gate
• 3-1/8 inch overall length for compact onboard utility use
• 5/16 inch ring diameter to match hardware and attachment points in this size
• 575 lb maximum safe load for general attachment and tie-down work
• Hand-operated closure for jobs where the connection needs to be removed and repositioned during the day

Compatibility and fit

This hook is a practical replacement when your current hardware is a 5/16 inch snap hook and you need about 3-1/8 inches of overall length. Before ordering, check the ring diameter, the clearance around the gate, and the space around the fitting or eye it will clip into.

It suits removable connections for dockside and onboard gear better than permanent attachment points. That makes it a sensible option for owners who move lines and accessories around during a trip and want a clip that opens and closes by hand.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
