Sea Catch TR7 with D-Shackle Safety Pin – 5/8" Shackle

The Sea Catch TR7 with D-Shackle Safety Pin (5/8") is a premium-grade quick release hook system engineered for strength, safety, and reliability in demanding marine environments. Designed for high-load applications, this robust release mechanism is ideal for towing, mooring, anchoring, and other critical operations where controlled release under tension is essential.

Heavy-Duty Quick Release Performance

The Sea Catch TR7 is built to handle substantial loads while providing a smooth, dependable quick-release function. Its precision-engineered trigger mechanism allows for safe disengagement even under load, making it a trusted choice for professional mariners, offshore operations, and safety-conscious boaters.

Integrated 5/8" D-Shackle with Safety Pin

This model includes a 5/8-inch D-shackle with a secure safety pin, offering a strong and reliable connection point for lines, chains, or rigging hardware. The safety pin ensures the shackle remains firmly locked in place during operation, reducing the risk of accidental release.

Built for Marine Durability

Constructed from high-strength, corrosion-resistant materials, the Sea Catch TR7 is designed to withstand harsh saltwater environments, heavy use, and extreme conditions. Its rugged design ensures long-term performance with minimal maintenance.

Key Features:

• Toggle-Linkage Principle: The mechanical design acts similarly to locking pliers, providing a firm grip that stays locked until the release lever is activated. This ensures a low-friction, low-effort release regardless of the load weight.

• Release Under Load: Specifically designed to be tripped via a lanyard from either a perpendicular or parallel angle, allowing for remote activation while lines are under full tension.

• Spring-Free Reliability: The mechanism contains no internal springs that could rust, lose tension, or fail in harsh saltwater environments, ensuring long-term mechanical consistency.

• Safety Lock: Every unit includes a hitch-pin safety lock (D-Shackle Safety Pin) to prevent accidental tripping during transport or in rough sea conditions.
