Hospital door RD400

Overview
Closely manage access with the ASSA ABLOY RD400 series (RD3A / RD4A) access-control revolving doors. Designed for restricted-entry environments, these revolving doors separate indoor and outdoor zones to improve climate control and reduce air exchange, while providing controlled one- or two-direction passage. Emergency break-away wings enable rapid egress when required. Units are available in multiple sizes and are intended for direct installation on finished floors without special foundations.
