ERBA Marine coordinates technical selection and supply for the agreed marine-door, hatch, custom-closure or component configuration. Included drawings, documents, delivery scope, service support and applicable warranty route are stated in ERBA Marine’s written quotation.

SELECTION BEFORE SPECIFICATION
How to approach marine hatches
Published families and images help identify a starting point; verified vessel and closure data determine the final selection.
Marine Hatches
Marine hatches must be matched to deck location, clear opening, cut-out, coaming or flush interface, operating method, surrounding material and project documentation. This range separates substantially different fabricated, cast and light-duty constructions.
Published images and model codes are selection references. ERBA Marine confirms the exact dimensions, material, hardware, finish, teak treatment, applicable documentation and installation information before supply.
Information to confirm
- Deck location and required duty
- Clear opening and cut-out size
- Cast or fabricated construction
- Flush, raised, proud or teak-finished interface
- Handle, dog, handwheel, gas-spring and glazing choices
- Current certificate, drawing and installation requirements
