An electrical box support assembly for mounting an electrical box between a pair of studs is provided. The electrical box support assembly includes, but is not limited to, a pair of telescoping overlapping struts and a pair of engaging tabs detachably coupled with each end of the pair of telescoping overlapping struts. Each strut has a face to which the electrical box may be secured. Each of the pair of engaging tabs includes a first engagement member for primarily engaging a closed face of one of the studs and a side engagement member connected generally perpendicular with the first engagement member. Each end of the pair of telescoping overlapping struts may be detachably coupled at one of two positions on each engaging tab in order to accommodate electrical boxes of varying depths.

A nozzle head for dispensing sealant within a gap is provided. The nozzle head includes, but is not limited to, a body section and a port connected with the body section. The body section forms a primary channel through which sealant is dispensed. The primary channel forms an entrance through which sealant enters the body section and an exit through which sealant is dispensed from the nozzle. The port is connected with the body section and surrounds the exit. The port forms a chamber having a tip portion opposed to a rear opening. The chamber forms an angled path from the tip portion to the rear opening to trap and guide excess sealant within the chamber to the rear opening.

One example of the invention is a holding bracket for attachment to a fastening tool, the fastening tool having a barrel for firing a fastener, the tool defining a major axis, the holding bracket for holding overlapping portions of two members to be fastened to one another. An example holding bracket comprises a mounting portion configured for attachment to the tool and an extension portion extending from the mounting portion. A holding arm is attached to the extension portion and spaced apart from the mounting portion in the direction of the tool major axis to define a gap between the holding arm and the mounting portion, the gap for holding the overlapping portions of the two members for insertion of a fastener ejected from the barrel.
