The many advantages of the RISE system make it interesting to upgrade traditional sealing systems with RISE. Upgrading with RISE not only improves the fire rating, but also instantly doubles the usable space inside any block system transfer frame. Existing installations can easily be upgraded to the RISE sealing system using extension frames.

Another option is to install a frame around the existing transit frame spot welded to the deck or bulkhead.

To install the RISE extension frame the two halves are positioned around the cables and pushed into the transit frame. The 10 mm high flanges on the top and bottom of the extension frame correspond with the wall thickness of the block system transits. The flanges must be firmly seated against the transit frame. Then the bolts and nuts on the top and bottom flanges are installed.

For optimum stability the extension frame should be spot welded to the existing transit frame.

After installing the RISE extension frame insert sleeves are placed around each cable. The sleeves are pushed into the frame leaving 20 mm of free space at the front and the back of the transit. Finally a 20 mm layer of FIWA sealant is applied at both sides of the frame.
