Sea Catch is a release mechanism designed for the safe release of an object or line while it is under load. It is a quality product of McMillan Design, Inc.
Release yourself of unnecessary hazards.
Evaluate your quick release mechanism.
Every day, all over the globe, engineers, technicians and crew members find themselves faced with the daunting and often unpredictable task of releasing a heavy object while under load. There are those that insist on using pelican hooks and pin-shackles -- devices not meant to be released under load -- whose effort to release rises sharply with increased load. As if the job wasn't hazardous enough!
Many, though, have overcome the usual risks associated with this operation. They are using the simplest and most innovative design in quick release history -- a device designed exclusively for safe release under load -- the Sea Catch Toggle Release. The key is the combination of a proven toggle linkage principle, low friction, computer-generated parts and a lot of thinking about its jobs.
A sea plow is launched safely in the Atlantic.
A flowline bundle is installed safely on the seabed of the Gulf of Mexico.
A telescope is "crashed" safely in the Batman/Robin movie.
Oceanographic equipment is lowered safely for NOAA.
A mooring system is deployed safely by Lucent Technologies.
What makes the Sea Catch so revolutionary?
A well-thought-out design that anticipates reality: heavy sea conditions, corrosive marine environment, quick release kick-back, inadvertent release, and the occasional shock and lock-up of unanticipated overload. A multi-purpose design that offers a combination of features never seen before in a quick release: multi-directional releasing capabilities, on-load and off-load releasing, a hitch-pin safety lock to prevent inadvertent release, lanyard-style release for maximum user safety, parts precision-cut with water jet technology developed by OMAX from aerospace-grade stainless plate, easy connection to common shackles, no springs, and a user-friendly size.
Quick releases have to be specific.
Movie special effects, purse seine operations, rescue launch deployment, and equipment weighing 20 tons -- each pose a very different challenge. Sea Catch meets these challenges with models ranging from 1,000 to 50,000-pound capacities. In the last three years over 400 Sea Catches have played a significant role in safer releasing operations in many industries in 22 states and 15 foreign countries around the world. All feedback has been positive -- nothing but praise from engineers and users world wide.
Releasing an object under load need not be a daunting task any longer. Release yourself of unnecessary hazards. Release with Sea Catch.

OPERATIONAL TIPS
Device locking: The use of the hitch pin is not required to secure the device in the locked position. The linkage is designed so that, when locking the release lever, it snaps over-center (like a pair of vice grip pliers) and is held firmly locked even with no load on the device or the use of a hitch pin. The hitch pin is an added safety measure preventing inadvertent release and one is provided with each unit.
Release effort: The required effort to pull the lanyard of the TR7 to release a connected tensile load of 5,000 or 10,000 pounds is about the same; around 40 pounds.
Warning! Improper use of this device may cause injury. Hitch-pin must be used to prevent inadvertent release. Stay clear of all objects released under load. Do not exceed load capacity of this device.
