The ASI 04523 Manual Roll Paper Towel Dispenser accommodates one standard paper towel roll that measures 8 inches diameter and 8 or 9 inches in length. In addition, the dispenser stores one stub roll of towels that is 4 inches in diameter and 8 or 9 inches in length and draws towels from this smaller roll if the main roll becomes completely depleted. With its recessed design, the dispenser requires a rough opening that measures 15-3/4 inches in width by 20 inches in height by 9-5/8 inches in depth for proper installation. The unit is crafted from 22-gauge, type-304 stainless steel, except for the door and rear panel, which are made from thicker, 18-gauge stainless steel. To dispense towels, a push lever is provided in the front of the unit. The door is outfitted with a keyed tumbler lock to prevent theft of the towels inside, and the door is secured to the cabinet of the dispenser with a multi-staked piano hinge.
