black quartz stone sample display box,cardboard cap-pb2021
The PB2021 contact pads are made from EPDM rubber — the same material used in permanent outdoor gaskets. They won’t degrade, stain, or transfer color to light-colored stone surfaces.
PB2021 Product Overview
We engineered the PB2021 center of gravity 40% below the frame midpoint after studying how customers interact with stone displays. They lean slabs forward to see the polished face, and the rack must not move.
Natural stone slabs are heavy, irregular, and expensive to replace. The PB2021 was engineered around those realities — load-tested to 120kg per slot with a safety factor of 2.5.
The PB2021 was first prototyped for a Dubai-based stone importer who needed display racks that could survive in 45°C warehouse heat without the powder coat peeling. That prototype is still in service 4 years later.

Most of our display racks are modular. You can bolt additional units together to create longer display walls as your product line expands. Contact us with your current configuration for expansion compatibility.
What materials can the PB2021 hold?
The PB2021 is designed around natural stone and marble samples. Share your sample dimensions and weight with our team, and we will confirm compatibility — usually within one business day.
What if a part arrives damaged?
We photograph every order during packing. If any component arrives damaged, send us photos of the affected parts and packaging. Replacement parts ship at our cost.
Do you offer design assistance for showroom layouts?
Yes. Send us your floor plan with dimensions and our team will propose a rack configuration that balances product density with customer flow. This service is included at no charge for any order inquiry.
What surface finishing options are available?
Standard is matte black powder coating with acid pickling and anti-rust treatment. We also offer custom RAL color matching, chrome plating, and specialized coatings for outdoor or high-humidity environments.
