Roxtec KFO Cable Transit Frame
Roxtec KFO cable transit frames are a light-weight composite frame which is openable – the Roxtec frame is suitable for installation also around existing multiple or single pre-terminated cables and pipes in one opening.
Roxtec rectangular cable transit frames are used to provide a reliable cable sealing ensuring safety, efficiency and long-term operational reliability – Roxtec cable seals protect against fire, gas, water, dusts, pests, blast load and electromagnetic interference.

Installing Roxtec KFO Cable Transit Frames
Contact T&D should you require support on the installation of Roxtec KFO cable transit frames:
- 1. Divide the frame into two frame parts.
- 2. Lubricate all end surfaces of the frame parts with Roxtec Lubricant.
- 3. If cables are pre-routed, reconnect the frame parts around the cables. One frame part onto each side of the wall structure. Recessed bolt holes must point outwards, away from the wall structure.
- 4. If cables are pre-routed, you will have to cut the gasket in a 45° angle, on the short side, to be able to mount it.
- 5. Remove the protection foil from the gasket.
- 6. Apply the adhesive gasket onto the frame part that will face the structure. Do not apply it on the side with the recessed holes.
- 7. Place the frame parts with the gasket side against the wall and insert all bolts and nuts. Recessed bolt holes must point outwards, away from the wall structure.
- 8. Insert and tighten all the bolts to 7 Nm.
- 1. Make sure that all inside surfaces of the frame are free from dust or dirt. Lubricate the inside surfaces with Roxtec Lubricant, especially into the corners.
- 2. Adapt modules, which are to hold cables or pipes, by peeling off layers until you reach the gap seen in pic. 3. The halves may not differ by more than one layer.
- 3. Achieve a 0.1-1.0 mm gap between the two halves when held against the cable/pipe.
- 4. Lubricate all modules for the frame thoroughly, both the inside and the outside surfaces.
- 5. Insert the modules according to your installation plan (transit plan). It is recommended to seal cables / pipes at the bottom of the frame and put spare modules on top.
- 6. Insert a stayplate on top of every finished row of modules.
- 7. Continue to fill up the packing space of the frame, until one final row is left. See pictures “Packing space” for the full size of the space.
- 8. Before inserting the final row of modules, insert two stayplates.
- 9. Separate the two stayplates and insert the final row of modules between the stayplates.
- 10. Drop the upper stayplate on top of the modules.
- 11. Lubricate all sides of the wedge sparsely, except front and back. Please read the markings on the wedge and turn it correctly before inserting it in the top of the frame (standard position). Face with “Stayplate this side” must always face a stayplate.
- 12. Tighten the screws until full stop, approx 20 Nm (15 ft.lb.).
- 13. Attach the Wedge Clip to the wedge bolts to check that the wedge is properly tightened.
- 14. Optional wedge positions (anywhere within the frame).
