The PURELL® CS4 AWD Hand Sanitizer Dispensing System is our toughest design for demanding environments, like extreme temperatures and high-traffic areas prone to vandalism. Features include a rugged resin construction that holds up to extreme weather and temperatures, a secure barrel lock mechanism, and mounting options that mount the dispenser flush to the wall so it can®t be pried off. The manual dispenser has a large sight window that makes maintenance easy and requires no batteries.
