SELECTION BEFORE SPECIFICATION
How to approach approvals & installation guidance
Published families and images help identify a starting point; verified vessel and closure data determine the final selection.
Approvals & Installation Guidance
Marine closure documentation is product- and configuration-specific. A technical sheet, drawing, installation instruction or certificate must be checked for exact model scope, revision, validity, construction, limits and installation conditions before it is used.
This page separates preliminary local references from approval claims and explains the data the yard, designer, class, flag or owner may require. The exact deliverable document package is confirmed in ERBA Marine’s quotation.
Information to confirm
- Vessel type, project stage, installation location and exposure
- Verified clear opening, structural cut-out and corner radii in millimetres
- Surrounding structure, frame interface, available depth and drainage
- Hinge side, opening direction, travel envelope and access constraints
- Preferred material, finish, insulation, glazing or teak arrangement
- Locks, dogs, handles, closers, stoppers and emergency operation
- Required weathertight, watertight, fire, class or flag duty
- Required drawings, certificates, calculations and installation documents
- Existing model code, photographs and measurements for replacements
- Quantity, delivery country or port and required schedule
PUBLISHED FAMILY REFERENCES
Approvals & Installation Guidance families and model-code groups
Compare the published family descriptions below, then send the exact project data for confirmation.
Product-specific document scope
Exact model only
A certificate, drawing or technical sheet applies only to the identified model, revision, construction and limits.
Document currency
Revision + validity + availability
ERBA Marine reconfirms the current issue and public-supply status before a document is relied upon.
Installation interface
Opening + frame + structure + procedure
Yard drawings, tolerances, welding/bolting, sealing, drainage and surrounding structure must match the selected product.
Project acceptance
Class + flag + owner + yard
The project authority determines the required evidence and acceptance route for the exact supplied configuration.
Configuration rule: Do not transfer a material, size, dog, handle, glazing, pressure, fire-rating or approval statement from one model code to another. ERBA Marine confirms the exact selected configuration in writing.
