Description: Rely Hybrid Dispensers are the newest innovation in touchless electronic soap dispensing. When the batteries are low, the dispenser automatically converts to manual, "PUSH THE COVER" operation. Included is a large, removable and refillable tank with a 900 mL capacity for bulk soap. The low profile (4") and sleek design make it ideal for any application, including those with tight spaces. The long battery life, 80,000 cycles on 4 C-Alkaline batteries (not included), along with the durable, impact-resistant plastic construction ensures longevity.
