Hercules M-T-M Hatches

A Bespoke Solution to Through Deck Access

Hercules Made-to-Measure Hatches are high quality watertight deck hatches designed to meet your individual requirements.

They can be fitted into any type of deck and made to suit any size of rectangular or square aperture.

Construction and Operation

The frame is fabricated from a marine grade aluminium extrusion.

The cover is a marine grade aluminium tread plate reinforced with a pre-fabricated sub-frame, and is secured to the frame by our unique and innovative system of captive pull down bolts. The cover also has a rolled edge giving the neoprene seal maximum protection against damage.

Hinges can be fitted allowing the hatches to fold back flat to the deck or provide a watertight door in bulkheads.

The bolts can be quickly loosened or tightened using the speed brace supplied with each hatch. The captive bolts are marine grade bronze and once tightened render the hatch watertight.

Hercules made to measure hatches offer total flexibility without compromising strength, durability, water resistance or safety.
