Frames

The MCT Brattberg range of transit frames, for both welding and bolting, meet the stringent demands of offshore and maritime applications. Frame units are cut, welded, ground and stamped with our logo, date of manufacture and material specification for identification and traceability. The complete frames are inspected and then dipped in a corrosion-resistant paint before being inspected for quality.

Frame types

• RGS is the standard frame for marine applications.
• RGSF is a frame with a flange that allows the frame to be welded into a hole which is slightly larger than the frame opening.
• RGSFB is a frame similar to RGSF except that it is bolted to the deck or bulkhead.
• RGSC is a frame with radius corners. 
• RGSK is an extended RGS frame for use on outer decks where pooling of water and debris is a problem.
• RGS btb is a double frame for packing from both sides enabling on-site pressure tests.
• RGB is the standard frame for land based applications.
• RGG is a standard bolt-on frame designed for plaster or light concrete walls.
• RGP is a round Lycron rubber frame for applications in holes and pipes.
• Sleeves are round steel frames which are used together with RGPs.
