The San Jamar Twin 9" Jumbo Tissue Dispenser (R4090TBK) delivers reliable tissue availability for commercial restrooms that require consistent performance. Its Infinity System ensures the spare roll remains protected until the first roll has been completely used, minimizing stub roll waste and supporting uninterrupted service during high traffic. This dispenser accepts a wide variety of jumbo bath tissue brands and grades, giving facilities flexibility in sourcing supplies. The built-in slider mechanism controls access to the second roll, reducing maintenance resets and helping staff manage paper rotation more efficiently. Constructed with a slim, break-resistant Black Pearl Oceans cover, the R4090TBK is suitable for restrooms with limited wall space. Its 12 × 19 × 5.25-inch profile blends into modern washroom environments found in restaurants, offices, schools, and other commercial settings.
