ABSTRACT:
A system for mounting a branch pipeline and sprinkler head assembly of a fire extinguisher sprinkler system to structural elements above the ceiling of a building in a manner which allows the sprinkler head to be vertically adjusted relative to the plane of the ceiling. The mounting system includes an anchor bracket which attaches the horizontal pipe of the branch pipeline to a structural element and a clamp which is attached to a structural element and is selectively operable for gripping and releasing the vertical pipe of the branch pipeline to allow vertical adjustment of the sprinkler head and hold it immobile subsequent to the vertical adjustment. The clamp is of special configuration which allows it to be operated in response to an operating force which is applied thereto in a direction parallel to the vertical pipe through a sprinkler head clearance hole formed in the ceiling.
