The ASI 0864-011-25N replacement part is used to convert the sanitary napkin dispensing portion of the ASI 0864 unit to accept $.25 coins. The dispenser contains two coin mechanisms, and so to fully change the sanitary napkin and tampon dispenser to charge a rate of $.25 per product, it is necessary to purchase the 0864-011-25T Tampon Coin Mechanism replacement part. Inside of the unit, the coin mechanism is fastener mounted, allowing for easy changing. Deposited coins are kept safe inside of a locked box, which is keyed differently than the main lock featured in the door of the ASI 0864 dispenser. This allows you to limit access to the coinage to specific authorized personnel among your maintenance staff, while still enabling all of your maintenance and housekeeping workers to open the unit to replenish supplies.
