Happy Tree (12 Pack) 1/2" IPS Fire Sprinkler Head Escutcheon Plate 3/4" Adjustment Range Recessed Two Piece Rosette Cover Trim Ring White Fire Sprinkler Covers for Ceiling

🔥【RIGHT SIZE】- This fire sprinkler trim ring fit perfectly 1/2" fire sprinkler head, and for both residential and commercial use. Recessed sprinkler head escutcheons are designed for recessed installation with certain pendent and horizontal sidewall fire sprinklers🔥【IMPROVE FUNCTION & DECORATION】- Absence of an sprinkler escutcheon to cover a clearance hole can delay the sprinkler head operation in a fire situation. Two-piece flush escutcheon is used to improve the overall appearance of a sprinkler installation by concealing the clearance holes required for the connecting piping and fittings to the sprinkler. Fire sprinkler covers are intended for use in areas with finished walls or overhead ceilings🔥【EASY TO INSTALL】- The separable two-piece design allows installation of the sprinklers and pressure testing of the fire protection system/evaluation of leak tightness, prior to installation of a suspended ceiling or application of the finish coating to a fixed ceiling. It also permits the removal of suspended ceiling panels, for access to building service equipment, without having to first shut down the fire protection system and remove sprinklers🔥【ADJUSTMENT DESIGN】- Each two-piece escutcheon provides for recessed sprinkler installations having total adjustments 19.1mm(3/4”) from the flush position. The adjustment provided by these escutcheons reduces the accuracy to which fixed piping to the sprinklers must be cut, while providing a decorative recessed sprinkler installation🔥 【NOTICES PLEASE】-These fire sprinkler covers for ceiling are only for 1/2” sprinkler head, not for 3/4” sprinkler head. The semi-recessed escutcheons must be installed and maintained in compliance with the applicable standards of the NATIONAL FIRE PROTECTION ASSOCIATION (NFPA). The owner is responsible for maintaining their fire protection system and devices in proper operating condition
