Introducing the Z4100

The PROFLOOR RM Series Z-4100 is a center bar seismic floor expansion joint cover for interior and exterior floors where thermal and multi-directional seismic movement is expected. Extruded aluminum support profiles carry an aluminum or stainless steel cover plate on a steel turnbar assembly, and the plate stays flush with the floor finish in service. It suits heavy pedestrian and medium vehicular traffic. The ZK-4100 variant closes the joint against a wall.

water protection

the clip-in water barrier. feel secure with the satisfying snap as the clip-in water barrier locks into place, shielding against leaks. with 300% elongation, it adapts to movement while maintaining integrity. no anchor bolt punctures mean superior protection, even in open-to-sky locations. heat-weldable tpe forms seamless intersections, eliminating weak points. the barrier holds water during rain or washing, then allows evaporation once the source stops. save time with quick installation and enjoy long-lasting protection. experience the simplicity and reliability of the clip-in water barrier
