The ASI 5002 Disposa-Valve Soap Dispenser accepts pre-packed cartridges that contain soap, hand lotion, heavy-duty cleaner, waterless cleaner or antiseptic soap, providing supplies for up to 1,500 washings. These cartridges have an attached heavy-duty vinyl soap valve, meaning that with each new cartridge the valve is also replaced. The dispenser is crafted from durable, 18-gauge, type-304 stainless steel. The door to the unit is secured to the body with a multi-staked stainless steel piano hinge. A keyed tumbler lock is featured at the top of the unit to prevent the theft of the internal soap cartridge. To dispense the soap, a zamak lever is included in the design. All of the exposed surfaces of the soap dispenser have a satin finish, which minimizes the appearance of fingerprints, but still retains an attractive gleam. The unit has a recessed design and requires a rough opening that measures 5-3/4 inches in width by 13-1/2 inches in height by 4-1/4 inches in depth.
