NPT and the Style 40 for 3\/4 in. NPT. Each gives 1\/2 in. (12.7 mm) of recessed adjustment, or up to 3\/4 in. (19.1 mm) of total adjustment from flush. The data sheet is explicit: use only the Style 10 or 40 escutcheon for recessed pendent installations.<\/p>\n<p>These are standard response, standard coverage sprinklers that TFP151 describes for light, ordinary and extra hazard commercial occupancies. Approvals (UL, FM, LPCB and others) vary by temperature rating and finish, so check the approval tables for the exact model before the submittal goes to the consultant.
