Hardware: Hydraulic support struts, engineering-plastic handles with safety locks, and stainless steel fasteners—all resistant to degradation in marine environments.
✅ Structure
Rectangular, rounded-corner, top-hinged porthole, available in two configurations:
1.Dual Hydraulic Strut + Dual Latch: Features symmetrical hydraulic supports and dual locking handles for balanced load distribution and superior stability.
