Hand hygiene product costs are measured by cost-per-push, and determined savings by dividing the cost of the product by the number of hand washes. Symmetry Hand Hygiene offers one of the best cost-per-push in the industry. Symmetry dispensers are made of durable ABS plastic equipped with interlocking ribs and anti-vandalism posts. Require less than 5 lbs. of pressure to activate and are operable with one hand. There is no tight grasping, pinching, or twisting of the wrist. Allow for both foam and liquid hand hygiene products. One dispenser meets all needs. Patented "No-Drip" foam bellows ensures a clean countertop after every push.
