Where it Works

Healthcare

Low energy operators offer reliable ADA access; promote safety and security and offer touch free functionality by helping reduce spread of germs and offer convenience and ease of use. The D4990 low energy operator is ideal for applications found in all hospitals or medical facilities.

Retail & Commercial

This promotes ADA and touch free environments helping reduce spread of germs and offers both convenience and ease of use that are attractive for retail and office environments.
