This is a Floor to Floor Thermal Expansion Joint Cover adaptable to many floor finishes, featuring recessed-mount frames that minimize sight lines. A snap-fit design provides for easy on-site assembly. The dual flexible seals offer a secure fit and yet retain optimal flexibility and absorb limited serviceable seismic movement. Extra wide joint widths are available, as well as an optional vapor barrier that slides into the frame for easy installation. Additional options include water & fire barrier.
