Abstract: A support device can have an opening to receive electrical cable or conduit and a gate that is configured to bend between an open configuration and a closed configuration relative to the opening. A locking tab can be provided configured to be selectively engaged with the gate to secure the gate in the closed configuration.

Abstract: A mounting bracket is provided for an electrical device that can be configured for use with a support that has a first and a second rail. The mounting bracket can include a mounting body with a mounting face configured to secure the electrical device to the mounting bracket between the first and second rails when the mounting bracket is secured to the support. The mounting bracket can include a first attachment device connected to the mounting body and a second attachment device connected to the mounting body opposite the first attachment device. Each of the first and second attachment devices can include a first arm configured to engage with a first side of the corresponding first or second rail, and a second arm configured to engage with a second side of the corresponding rail, opposite the first arm.

Abstract: A device for securing threaded rod relative to concrete and plywood forms is provided. The device can include a housing with a securement portion and a plurality of plungers to engage with the threaded rod. The securement portion can be slidably received in a base configured to be seated on a setting structure. Fasteners can secure the device to the setting structure. A tapered portion of the housing can engage the plungers to secure a threaded rod.

Abstract: A bracket system for securing an electrical box and other components to a ceiling structure can include a support structure and a mounting bracket. The mounting bracket can include a first support member and a second support member that define a support channel for slidably receiving the ceiling member. The mounting bracket can further include a first contact member and a second contact member that extend from the second support member and define a contact channel to slidably receive the attachment end of the support structure.

Abstract: A bracket for adjustable-depth mounting of an electrical box relative to a support structure can include a support body and a support arm. The support body can be configured to be secured to the support structure. A fastener can be retained on the support arm and can be adjusted relative to the support arm to move the electrical box to be secured at any of a plurality of depths relative to the support body.

Abstract: A mounting bracket for an electrical box can be configured for use with a support that has a first and a second rail. The mounting bracket can include a first attachment device that is secured to mounting body and a second attachment device that is secured to the mounting body opposite the first attachment device. To secure the mounting bracket to the support, the first attachment device can be configured to engage one of the first rail or the second rail and the second attachment device can be configured to engage the other of the first rail or the second rail.

A locking tab can be provided configured to be selectively engaged with the gate to secure the gate in the closed configuration.

Abstract: A mounting system for a first support and a second support for electrical components can include a first mounting interface and a second mounting interface. The first mounting interface can include a first channel, and a first insertion slot extending from inside of the first channel to outside of the first channel. The second mounting interface can include a second channel and a first interface arm, and a second interface arm. The second channel can be configured to nest with the first channel. The first interface arm can extend through the first insertion slot when the second channel is nested with the first channel.

Abstract: An apparatus and method are provided for replacing existing actuator driven zone valves in an HVAC system, and particularly valves of the rubber paddle type having actuators providing less than 90 degrees of rotation, with a ball valve including a skewed seat bearing that blocks flow through the flowpath when a valve member of the ball valve is rotated through an angle of substantially less than 90 degrees from a fully open position of the valve at which a bore in the valve member is substantially fully aligned with the flowpath. The actuator from the existing zone valve being replaced may be used with the provided ball valve apparatus and method.

Abstract: A valve apparatus includes selectively releasable engagement apparatus for operatively connecting an actuator to a valve body of a valve having an operating member extending outwardly from the valve body along an axis of the operating member are provided. The engagement apparatus includes a latch arm extending from the valve side of a base, rather than the actuator side of the base. A plurality of protrusions on the valve body and corresponding mating receptacles on the base resist torque forces on the base. A slot in the base adjacent an edge of the latch arm provides passage for tooling used in forming the base. A base in the form of an adapter allows attachment of an actuator not having a selectively releasable engagement apparatus to a valve body that does include a selectively releasable engagement apparatus.

Abstract: An apparatus and method are provided for modifying a flow characteristic, such as a valve characteristic, through use of a flow characterizing device having a segmented flow characterizing channel therein including three or more discrete segments, at least one of which is a through-hole, for modifying a flow of fluid through a flowpath, in which the flow characterizing device is mounted, when a controlling edge, mounted in the flowpath adjacent the flow characterizing device, is aligned with one or more of the three or more discrete segments of the flow characterizing channel. Either or both of the flow characterizing channel and the controlling edge are selectively movable relative to one another.

Abstract: A manual override mechanism is presented for a motor-driven linear actuator that allows the output rack and pinion of the actuator to be manually positioned. Once positioned, the output may be locked by a locking mechanism to prevent this output from translating to its quiescent position. When incorporated in a spring-return linear actuator, the manual override may be used to apply a preload on the spring before the driven device is connected. When the actuator is used to drive a valve or damper, the preload applies a positive closing force on the valve or damper in its zero position to ensure a tight closure of the valve or damper. The locking mechanism engages the gear train and opposes the closing force applied by the spring return of the actuator. To disengage the locking mechanism automatically, the motor applies a forward kick to the gear train. Manual disengagement is also provided.
