FlexHead® Industries' Institutional Connections
September 1, 2005

FlexHead® Industries, the inventor and patent holder of several types of flexible sprinkler connections, announced it has launched a new sprinkler product line for use in institutional applications. Installers can connect any tamper-resistant institutional sprinkler head to the branch line through a concrete wall or ceiling using flexible stainless-steel hose and retaining flange. Installs at least five times faster than traditional black iron pipe.
