Abstract: A picture hanging device having a top member with a lower linear edge, a bottom member with an upper linear edge in parallel relationship to the lower linear edge of the top member, and a level connected to at least one of the top and bottom members. The top member is slidably connected to the bottom member so as to vary a distance between the linear edges. The level is a bubble level for indicating when the linear edges are extending in a horizontal plane. The upper and lower linear edges are angled from a back side to a front side of the device. The upper linear edge of the bottom member has a plurality of nail-receiving slots formed therein.

Abstract: An apparatus for securing equipment to mounting surfaces includes two clamps connected by a strap. One clamp is adhesively mounted to the mounting surface and the second clamp is adhesively mounted to the equipment. Latches pivotally mounted on the top of the clamps include a protrusion, and the strap has holes formed therein. When the latch is pivotally locked onto the strap, the protrusion extends through one of the holes and into a cavity in the base of the clamp. The protrusion also includes a forward corner that is distorted upon pivoting the latch to cause the latch to lock down onto the strap.

Abstract: A track assembly for suspending an elongated duct from a supporting structure includes a rail assembly formed from a plurality of cylindrical tube segments and a plurality of splicer members interconnecting the tube segments in end to end relationship. The plurality of elongated hanger members are detachablely connected to the rail assembly and are adapted to be connected to a supporting structure. A plurality of slide members are mounted on the rail assembly for sliding movement along the length thereof past the splicer members and the hanger members. Each of the slide members has a clip attached thereto capable of detachable securement to an elongated duct.
