BOLT-ON FRAME SECTION DATA
These require fixing holes to be drilled in the vessel around the edge of the aperture. The frames are usually drilled at between 100mm and 150mm intervals. There are three different interior trim options:
-
Type 1: A flat interior trim ring which is fixed using machine screws (external) and interscrews (internal).
-
Type 2: A channel section interior trim which is fixed using self-tapping screws from the outside. There are no visible fixings on the interior frame for the Type 2 trim.
-
Type 3: Predominantly for thicker wall/hull sections, the Type 3 trim incorporates a spigot (maximum depth 75mm) to cover the inner edge of the aperture and a profiled interior trim ring which is fixed using either machine screws (external) and interscrews (internal) or self-tapping screws inside and outside.
