Additional sea catch products

Sea Catch products are widely used and trusted worldwide as the simplest and innovative quick release hooks available. Sea Catch uses the proven toggle linkage principle to both lock and release lines or objects under load. Models range from 0.59 to 69.96 tonne capacity. 

Sea catch spring safety pin

The purpose of the spring safety pin (SSP) option is to allow the user to pull the pin from a distance.

Comprised of spring safety pin, R-clip, tether cable and end fitting, and a short red release lanyard attachment line, the mechanism can be fitted on hooks currently in use or supplied with purchase of a new hook.

Sea catch LM series hooks

The LM series up to the TR12 have an enlarged and reinforced jaw area able to accept larger diameter wires and shackles than the standard Sea Catch.

The TR15LM is a modified TR15 provided with a front jaw enlarged to receive up to 2.98″ fibre line such as a fibre forerunner. Additional side plates at the jaw area are provided to spread the load. An inner jaw radius of 1.61 inches is formed to simulate the synthetic line end of a Mandal Fairlead Shackle #120M.

Sea catch TR15DM

The TR15DM is a modified TR15 provided with a front jaw enlarged to receive up to 3.3″ fibre line such as a fibre forerunner.

Additional side plates at the jaw area are provided to spread the load. An inner jaw radius of 1.61 inches is formed to simulate the synthetic line end of a Mandal Fairlead Shackle #120M.

Sea catch air-activated units

Standard Sea Catch units are fitted with a hole in the body below the release lever and mounting holes tapped in the base of the body.

The rod end of an air cylinder is inserted into the hole and the cylinder is mounted below the body with thru-mounting screws. Air-activated Sea Catches operate at 60 to 100 psi. Manual backup release is maintained by means of the standard lanyard pull on the release lever.

Sea catch hydraulic-activated units

The Sea Catch RAM hydraulic activated unit is a standard Sea Catch model fitted with a hydraulic cylinder mounted below the device.

Above the cylinder is a plunger which penetrates through a hole in the body below the toggle pin. When activated, the cylinder pushes the plunger and the toggle pin upward causing the Sea Catch to release. The usual manual release capability is maintained. The maximum hydraulic pressure for all hydraulic cylinders is 5,000 psi.

Sea catch squib-fired units

Sea Catch Squib-fired models are standard Sea Catch units fitted with chambers below the release lever where a squib or squib-fired thruster is threaded or inserted and secured. The units are electrically, often remotely activated.

The Sea Catch TR5SQ and TR7SQ can now be fired solely with a squib although the use of squib-fired thrusters offers far greater dependability, firing consistency and safety. With the TR5SQ and the TR7SQ, safe, split second release activation is provided for both single load or multiple load releasing. Manual backup release is maintained by means of the standard lanyard pull on the release lever.

Sea catch TR7RL

The Sea Catch TR7RL is simply a Sea Catch TR7 with a release lever that is reversed.

This modification allows the operator to activate the unit from the side of the unit (perpendicular to the line of load) or slightly below that direction. Special care must be taken to stay clear of objects being released under load.
