The PURELL® CX10 Automatic Counter Mount Soap Dispenser Retrofit Kit lets you update existing PURELL® CXi (8520-01) and CXT (8540-01 and 8550-01) spouts with the CX10 dispensing system. The CX10 is an always ready dispenser that keeps restroom walls uncluttered without a labor-intensive refill process. It requires less maintenance thanks to a fresh battery built into every refill, so you never have to change or buy batteries (under normal conditions for lifetime of dispenser or 10 years). Easy-to-replace refills don't require feeding tubes or reaching to the back of the sink. Simplify work even more with optional SMARTLINK® capabilities that can send you service alerts (sold separately). Always primed and ready, the CX10 fits nearly any sink with extended tubing and wiring for flexible installation.
