The Bradley 644 soap dispenser provides 32 ounces of liquid hand soaps and lotions that contain 10 to 15 percent coconut or vegetable-based soap for use in commercial restrooms. The entire unit is made of type-304 stainless steel with an 18-gauge faceplate, and has a stainless steel soap vessel. This model is outfitted with a keyed tumbler lock to prevent vandalism. Crafted from chrome-plated brass, the valve can be depressed with less than 5 pounds of pressure, allowing the unit to comply fully with ADA and other barrier-free accessibility guidelines. For convenience, the dispenser is refillable even when soap remains in the unit. A sight gauge featured in the unit makes it easy to monitor how much soap remains inside of the dispenser's high impact molded polystyrene soap vessel. All of the exposed surfaces feature a satin finish. Overall dimensions: 6 W x 10 H x 4 D Rough wall opening required: 4-1/2 W x 8-1/2 H x 4 D
