In one aspect there is provided a pipe spinner and lifter for supporting and rotating a cylindrical member having a longitudinal axis. The pipe spinner and lifter comprises a pair of jaws that pivot about a pivot member, to allow the pipe spinner and lifter to actuate between an open configuration and a closed configuration. A plurality of rollers are mounted on the jaws, each rotatable about a rolling axis. When the pipe spinner and lifter is in the closed configuration, the cylindrical member can be rotatably captured by the pipe spinner and lifter, allowing the cylindrical member to rotate about its longitudinal axis. Preferably, the plurality of rollers are arranged in a substantially mirrored arrangement on the jaws. More preferably, the rolling axis of each of the rollers is substantially parallel to the cylindrical member's longitudinal axis.

An automatic locking mechanism can include one or more annular elements having teeth facing each other or facing away from each other. The automatic locking mechanism can include a rod disposed between the annular elements. The rod can have one or more pins configured to interface with the teeth of the annular elements. The pins and the teeth are also configured to rotate the rod when the annular elements move relative to the rod. The rotation of the rod can toggle a hook end of the rod in a hook receptacle, which can change states of the locking mechanism.

A ceiling-mounted device support includes an engagement portion to be engaged with an attachment portion of a ceiling-mounted device mounted on a ceiling surface of a room with an adapter, and includes a side wall having an open upper end, an open lower end, and an internal space, and a support portion having two ends connected to the side wall and extending through the space. The engagement portion is to be engaged with the attachment portion, and the support portion is supportable with a palm and grippable with digits of a hand.
