The FlexHead® Institutional Sprinkler Connection uses our UHO-3 Bracket (retaining flange) to secure the flexible sprinkler hose to the concrete wall or ceiling.
These connections have been specifically designed for use in institutional mental health occupancies, correctional facilities, or anywhere a likelihood of tampering with fire sprinklers by the occupants may exist.
The institutional sprinkler connection consists of a flexible hose in lengths from 2-6 feet and a retaining flange; and is approved for use with pendant or sidewall institutional sprinkler heads. These connections are designed to be installed in concrete wall or ceiling penetrations using institutional sprinkler heads. They are compatible with any institutional sprinkler head on the market.
- FlexHead® institutional sprinkler hose: 304 stainless steel
