A hub assembly for supporting a portion of a flexible sprinkler assemblage within a ceiling, the hub assembly including a primary support mounted to a ceiling support member, and a secondary support member rotatable relative to a primary support member between an open position and a closed position. In the closed position, portions of the supports are overlapping and cut outs formed in the primary support cooperate together with cut outs formed in the secondary support to define a hub opening configured to receive the portion of the flexible sprinkler assemblage. The hub assembly also includes a locking mechanism configured to selectively connect the primary support to the secondary support, and an adjustment mechanism disposed on the primary support that is configured to secure the position of the portion of the flexible sprinkler assemblage within the hub opening, and is separate from the locking mechanism.

Hub with locking mechanism

A system is provided for maintaining a sprinkler head in a position to allow continued operation during a fire in the event that the support structure for the sprinkler head fails or is otherwise removed. The support system includes a central hub adapted to receive a sprinkler head, a first leg attached to the central hub and having first and second ends. The support system also includes first and second ends having fastening devices adapted to attach the ends to the support structure. The fastening devices are configured to break away from the support structure in the event of support structure failure.

Support system attachment mechanism for fire protection sprinklers

A support system for positioning a sprinkler head relative to a support structure in a ceiling, floor, or wall includes a central hub adapted to receive the sprinkler head, a first leg attached to the central hub and having a first end configured to be attached to the support structure, a second leg attached to the central hub and having a second end configured to be attached to the support structure, the second leg being spaced-apart from and substantially parallel to the first leg. The support system combines increased flexibility in installation with increased support for the sprinkler head during operation.
