Using this dispenser is easy. Just install it in the semi-recessed space in your commercial restroom following the size requirements. Open the door with the key for the tumbler locks and load the tampons and sanitary napkins into their respective compartments. When someone needs a product, they can take it for free. Remember to keep the key in a safe place to prevent unauthorized access. For maintenance, regularly check the dispenser to make sure it's well - stocked. Wipe the satin - finished surfaces with a soft cloth to keep them looking good and to remove any fingerprints. If you notice any damage to the locks or the hinge, get it repaired right away to keep the dispenser secure and functional.
