Concealed sprinkler

Concealed sprinklers thread onto Uponor's fire sprinkler adapter fittings. All sprinklers come complete with a plastic protective cap and cup. Sprinklers are NSF- and UL-approved for combined plumbing and fire sprinkler systems. Sprinklers designated LF are also NSF Annex G compliant. Note: Concealed cover plates for LF74970FC sold separately. Concealed cover plates are included with LF74971FW. Do not store sprinkler assemblies where the ambient temperature will exceed 100°F. Special sprinkler wrenches are required to assemble sprinkler and adapter.
