Strength

As the name suggest Hercules Hatches are very strong.

The hatch cover and flange ring are cast from corrosion resistant marine grade aluminium, with deep section webs on the underside to prevent distortion under load

Durability

All moving parts are engineered from type 316 marine grade stainless steel. All components are made to exacting standards and proportioned with strength and reliability in mind.

The bushes and bearings fitted to Hercules Hatches are manufactured from hard wearing Ertalyte, with replacements being readily available and easily fitted. In fact anything that might wear is easily and inexpensively replaceable, so a Hercules Hatch will last as long as the vessel itself.

Water Resistance

Hercules Hatches offer exceptional waterproof integrity for a deck hatch.

Hercules Hatches have a fuel and chemical resistant neoprene sealing ring fitted to the underside of the cover giving maximum protection against damage.

Ease of Operation

The unique Hercules locking mechanism utilities large diameter stainless steel shooting bolts which engage in Ertalyte bushes within the frame. This mechanism makes the Hercules Hatch exceptionally smooth in operation.

On deck the hatch is opened and closed using a recessed handle which is lifted and turned through 90 degrees. Below deck it is operated by a hand wheel.

Safety

The locking mechanism is precisely engineered for strength and security. Once the shooting bolts are engaged, the hatch cannot be accidentally opened.

Hercules Hatches are designed to withstand years of punishment in the harshest of marine environments.

Accessories

Hinges can be fitted to allow Hercules Cast Hatches to open and fold back flat on the deck or to provide a watertight door in bulkheads. For extra security whilst in port, Hercules Hatches can be locked from below deck by using a simple sprung stainless steel clip on the bolt mechanism.
