Abstract: A device and method for protecting and installing a fire protection sprinkler. The protective and installation device has two discrete protective members coupled to one another about the sprinkler by a connection between the two discrete protective members that includes a releasable locking arrangement. At least one of the members includes a torque assist portion for applying torque to the fire protection sprinkler and each of the members includes a deflector protection portion. The discrete protective members include projections that extend toward each other to overlap each other and surround a maximum radial extent of frame arms of the sprinkler.

Abstract: Institutional sprinkler assemblies are provided that includes a sprinkler housing and protective cap arrangement to protect a thermally responsive shielding trigger. The sprinkler housing and trigger arrangement provide for an annular buffer to protect the trigger. The institutional sprinkler assemblies include configurations for installation in pendent and horizontal and orientations.

Abstract: A fire protection sprinkler assembly having a frame that includes a pair of frame arms configured with a geometry that strengthens the frame arms to resist impact, shear and/or torsional loads. The sprinkler assembly can be configured for installation in any one of an upright sprinkler, a pendent sprinkler, horizontal sidewall sprinkler or a recessed sprinkler.
