Raised Square Scuttle Hatch

Reliable Access for Demanding Marine Environments

The UMC‑615 Quick‑Acting Hatch is engineered for vessels that need fast, secure, and watertight access without slowing down operations. It’s built for workboats, offshore vessels, military craft, and commercial ships where durability and safety are non‑negotiable.

Fast, One‑Motion Operation: Crew members can open or secure the hatch in seconds, improving workflow during routine checks, maintenance, or emergency situations.

Watertight Protection: Designed to withstand harsh marine conditions, the UMC‑615 maintains a tight seal that protects against water ingress, pressure changes, and rough seas.

Built for Heavy Use: Constructed from marine‑grade materials, it resists corrosion, impacts, and long‑term exposure to saltwater environments.

Versatile Installation: Ideal for decks, bulkheads, and compartments where quick access is essential—engine rooms, storage spaces, and technical areas.

Safety‑Focused Design: The quick‑acting mechanism reduces strain on crew members and ensures consistent sealing performance, even in demanding conditions.
