Abstract: Provided herein is a fire sprinkler assembly including a bracket hub coupled to a bracket bar, and an adjustable drop coupled to the bracket hub. The adjustable drop may include an inner casing and an outer casing surrounding the inner casing, wherein the inner and outer casings include corresponding threading to permit rotation therebetween for adjusting an axial height, along a lengthwise axis, of the inner casing. In some approaches, a flexible metal conduit is directly coupled to a distal end of the inner casing or the outer casing. In some approaches, the inner casing includes a bellow disposed within an interior of the outer casing, the bellow having an expandable central component permitting contraction or expansion, which allows a sprinkler head coupled to the inner casing to be raised or lowered, accordingly.

An interior angle between the set of plates and the bracket bar is less than 90 degrees (e.g., 80-85°). The bracket assembly may further include a seating frame extending from a second end of the set of plates, the seating frame including a first member and a second member disposed on opposite sides of the beam. The fire sprinkler support assembly may further include a fastener extending through an opening of the upper wall to couple the set of plates to the bracket bar.

In one approach, a support assembly includes a bracket bar extending transverse to a beam, and a bracket assembly coupled to the bracket bar. The bracket assembly may include a first plate oriented substantially perpendicular to the bracket bar, the first plate having a first end coupled to the bracket bar and a second end, opposite the first end, coupled to the beam. The bracket assembly further includes a seating frame extending from the second end of the first plate, the seating frame including first and second members disposed on opposite sides. The bracket assembly further includes a second plate rotatable relative to the first plate, the second plate having first and second ends disposed on opposite sides of the beam, and a fastener coupling together the first and second plates.

Abstract: An adjustable bracket includes a first bracket portion with a first leg and a first bar element, a second bracket portion with a second leg and a second bar element, and a hub assembly supported on at least one of the first and second bracket portions. The hub assembly can be configured to couple a flexible hose to the adjustable bracket. The first bar element can be telescopically received by the second bar element so that a distance between the first and second legs is selectively adjustable. A fastener can fix the first and second bar elements in a desired relationship. The hub assembly can include first and second support members that are pivotably connected to rotate between open and closed positions. The second support member may have a slot that allows the second support member to rotate and move laterally with respect to the first support member.

Abstract: A bracket assembly includes a main body, the main body including a first set of seating members extending downwards from the main body; and a support arm extending laterally outward from the main body, the support arm includes a shaft oriented perpendicular to the main body, and a second set of seating members extending downwards from the shaft.

Abstract: A method of installing a pipe coupling to connect a first pipe element to a second pipe element includes sliding the pipe coupling as a preassembled unit over an outermost surface of the first pipe element, the pipe coupling comprising a coupling segment and an annular gasket, the annular gasket comprising an annular body and a pair of sealing ribs extending substantially radially inward from the annular body, each sealing rib comprising a sealing ridge defining a sealing surface, the sealing surface of each sealing ridge being coannular in an undeformed state; introducing an end of the second pipe element to an end of the first pipe element to place the first pipe element and the second pipe element in end-facing relationship; aligning the pipe coupling over the first pipe element and the second pipe element; and securing the coupling to the first pipe element and the second pipe element.

Abstract: A mechanical branch outlet including: a housing having an outer surface and an inner surface and defining an outlet bore extending between the outer surface and the inner surface; and an insert having a first end and a second end, the outlet bore of the housing sized to receive the second end of the insert and retain the first end of the insert.

Abstract: A pipe joint assembly including a first pipe element, a second pipe element, a pair of segments, each segment defining a first end and a second end, each first end comprising a tongue and each second end comprising a groove, each groove defining a groove shoulder surface, the tongue of the one segment defining a tongue outer surface, the tongue outer surface of the tongue of the one segment angled at a non-zero angle relative to the groove shoulder surface in an assembled and untightened position, the tongue outer surface of the tongue positioned parallel and flush to the groove shoulder surface of the groove of the second segment in an assembled and tightened condition; and a pair of fasteners configured to deflect each segment around the first pipe element and the second pipe element in the assembled and tightened condition.

Abstract: Provided herein is a sprinkler system including a compact-design connector coupling a flexible conduit to a sprinkler body. In one approach a sprinkler assembly includes a t-joint connector, a sprinkler body (e.g., a dry-type pendent body) coupled to the t-joint connector at a first opening of the t-joint connector, and a flexible conduit coupled to the t-joint connector at a second opening of the t-joint coupling. The sprinkler assembly may further include an adjustable bracket coupling the sprinkler body to a building structure, such as a ceiling or wall. The t-joint connector eliminates the use of an elbow-type connection to a flexible hose, thus enabling use in a freezer/cooler application, while also reducing the overall footprint of the sprinkler assembly.
