BOLT-ON FRAME SECTION DATA

Bolt-on frames require fixing holes to be drilled through the vessel structure. The frames are usually drilled at between 100mm and 150mm intervals. There are two 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.
