Roxtec CF 8/32 Ex Cable Transit Frame

Sealing Cables & Cable Ducts

Roxtec CF 8/32 EX cable transit frames are cast aluminium frames which are suitable for compact installations in cabinets – the Roxtec frame is suitable for installation also around existing multiple or single pre-terminated cables and pipes in one opening. The transit frames are approved for use in potentially explosive atmospheres and hazardous locations.

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.

9b. If the gap is too big, the gauge will slip in easily.
9c. If the gap is correct, there will be no room for blade two.
10. When checking without the gauge, there shall be a visual gap.
