the z-4102 accommodates ±50% of nominal joint width in multiple directions. the continuous aluminum center plate, held by center machine screw and turn bar assemblies at 500 mm on center, stays flush with the floor and self-centers after seismic displacement.
an optional water barrier membrane can be specified with the z-4102. it is draped into the gap and retained by the base frames, so no mechanical punctures pass through the membrane sheet. order it together with the system.
rated 20 kn to 30 kn in the system drawings, depending on joint size, the z-4102 suits floors in airports, convention centres, hospitals and large public buildings.
this video demonstrates the assembly process, perfectly designed for easy installation for durability and reliability.
Continuous recessed aluminum frames, 30 mm to 43 mm high depending on joint size, hold a continuous aluminum center plate flush with the finished floor. One frame family covers joints from 30 mm to 300 mm, and the ZK-4102 variant closes the joint against a wall for a clean, low-profile transition.
