Nero Marquino Black Stone ADA Saddle Threshold Double Side Hollywood – Polished / 2 in / 24 In

Yes, the Double Side Hollywood design features deep bevels on both sides to create a smooth ramp profile, making it fully ADA compliant for wheelchairs, walkers, and high foot traffic. To ensure full compliance, we highly recommend our precision custom-cut service so the stone fits flush against your door jambs, leaving no dangerous gaps or uneven edges.

Engineered Quartz is non-porous and extremely dense, offering superior durability against heavy wheelchair and commercial traffic. Unlike natural black marble, it provides higher resistance to scratching and moisture. Using our custom width options up to 12" allows you to cover the entire depth of your door frame with a single, safe, and bold transition piece that never requires sealing.

Quartz is a very hard material that is prone to chipping, especially along the white veining, if cut with standard hand tools. Our custom size cut is performed using industrial wet saws with diamond blades, ensuring factory-smooth edges. This saves you significant time on-site and guarantees a professional finish that matches the high-quality beveled edges of the stone.

Measure the clear width between the narrowest points of your door frame at the floor level. For a professional installation, we recommend ordering your custom length 1/8" shorter than the total measurement. This prevents the piece from binding against the jambs during placement and provides a small, uniform gap for a clean caulk seal.

While both are highly durable, the Matte (Honed) finish is often chosen for ADA transitions because it provides slightly better slip resistance. The Polished finish offers a more reflective look that makes the white veining pop. Regardless of finish, our custom cutting ensures all edges are eased and safe for high-traffic use.
