proflex sm series
Introducing the OF-4000
seismic movement accommodation
handles thermal, settlement and multi-directional seismic movement of ±50% of the joint width; after each movement the turn bar assembly brings the cover plate back to the joint center.
water protection
the optional water barrier below the of-4000 carries water away along the joint, so the structure below stays dry as the joint moves.
load bearing
rated 30 kn in the system drawings for heavy pedestrian and light vehicular traffic, the 7 mm plate suits offices, hospitals, airports and retrofit projects.
assembly in action
this video demonstrates the assembly process, perfectly designed for easy installation for durability and reliability.
Aesthetic Choice
At only 7 mm high, the aluminum or stainless steel cover plate sits almost flush on the finished floor, keeping the joint discreet and easy to walk or roll across.
Optional Vapor Barrier
Galvanized Steel Turnbar Assembly
