Quick Release Hooks (QRH) enable mooring lines to be quickly and easily released, even under full load conditions. A variety of mounting options exist for the quick release hook. Typically a cast QRH base is used for new installations. To upgrade older facilities, fabricated hook bases can be designed to suit existing hold-down bolt patterns to replace bollards or old QRHs. THM hooks can also be retrofitted to existing bases from other suppliers, considerably reducing on-site civil works.

What is a Quick Release Hook?

A quick Release Hook is a mooring device designed to safely release mooring lines under tension with a single, controlled action. It enables fast vessel departure during routine operations or emergencies, reducing manual effort and improving dock safety.
Commonly used at ports, offshore platforms, and harbors, a quick release mooring hook minimizes strain on the crew and allows a quick response in situations like rough weather or equipment failure.
These hooks are compatible with bollards, capstans, and both manual and remote release systems. Built from corrosion-resistant materials and engineered to meet international marine safety standards, they offer reliable performance in demanding environments.

Types of Quick Release Hooks Offered by Lion Rubber
