Carbis TCEN and TCEN II SAF-T Enclosures are engineered to provide safe access to vehicles ranging from small, single hatch tank trucks to full-size hopper cars. Both safety enclosure systems contain standard 42" high handrail systems, and toeboard to protect workers from inward and outward falls. They can be manufacturered in lengths of up to 60" for hopper cars, and the TCEN II features a slip-resistant 19" inboard platform the full length of the enclosure.
