Introducing the Z-4050

The ECOFINISH Series Z-4050 is a compact pan-type seismic floor expansion joint cover designed for interior applications requiring a premium tiled finish without the cost of a full-scale pan system. The AA 6063-T5 aluminum hinged plates sit beneath a recessed pan that accepts tile, marble, or stone infill, letting the joint disappear into the surrounding floor. Ideal for boutique hotels, retail flagships, and hospitality projects where seismic protection must be invisible.
