Seismic Floor Expansion Joint Cover MSD-QSZ

Advantages
POP UP System with Seismic Re-Centering
Integrated centering bar and compression spring assembly automatically reposition the pan after seismic movement, ensuring long-term alignment and performance.
Zero Sight Line
Only two subtle rubber strips remain visible after installation — a flush, elegant finish highly preferred by interior designers. Engineered for high-grade marble, granite, limestone, and paver floors, blending harmoniously with surrounding luxury surfaces.
Silicon Sealant Matches Grout Lines
Color-matched silicon sealant system integrates seamlessly with grout lines in different floor designs, preserving visual continuity.
Seismic & Vibration Control Option
Configurable with shock-absorbing features for earthquake-prone areas, protecting both structure and finish during ground movement.
Adaptable to Various Joint Widths
Flexible design accommodates a range of joint widths while maintaining a clean, unobtrusive surface appearance.
Limitations
Limited Elastomeric Filler Weatherability
The elastic gel filler has moderate weather resistance. Over time, aging may cause visible cracking between the base and filler under tension, slightly affecting aesthetics. Under compression or stretching, the visible rubber strips may bulge or sink, creating slight unevenness — more noticeable with wider strips required for larger movements.
Lower Durability Compared to Metal
Rubber components have a shorter service life than metal alternatives and may require replacement after several years of use.
