## Abstract

A hanger assembly for attaching to framing. The framing has a first vertical wall and a second vertical wall. The framing also has a top and a bottom. The framing has two bearing surfaces that form a plane that is located between the top of the framing and the bottom of the framing. The two bearing surfaces form a slot that allows access to the interior of the framing. The hanger assembly includes a nut that engages the two bearing surfaces of the framing. The nut has a first thread. The hanger assembly also includes a threaded rod that contains a second thread that engages the first thread. The hanger assembly also includes a coupler that contains a third thread that engages the second thread. The distance between the nut and the coupling changes when the coupling is rotated with respect to the nut.

## Claims

### Claim 1

A hanger assembly for attaching to an associated framing, the associated framing having a first vertical wall and a second vertical wall, the associated framing having a top and a bottom, the associated framing having two bearing surfaces that form a plane that is located between the top of the associated framing and the bottom of the associated framing, the two bearing surfaces forming a slot that allows access to the interior of the associated framing, the slot having a width, the hanger assembly comprising:
a) a nut configured to engage the two bearing surfaces of the associated framing, the nut having a first thread;
b) a threaded rod containing a second thread that engages the first thread;
c) a coupler containing a third thread that engages the second thread wherein the distance between the nut and the coupler changes when the coupler is rotated with respect to the nut, the coupler further including a fourth thread that is an internal thread; and
d) a pipe that includes a fifth thread, the fifth thread being an external thread, the fifth thread engaging the fourth thread, the pipe having in inside diameter sufficiently large to accommodate the threaded rod without engagement of the second thread with an interior of the pipe, the threaded rod and the pipe forming a stem, the stem having a length wherein the length of the stem allows mounting of the hanger assembly from a floor or platform without a user having to be elevated.

### Claim 2 (depends on 1)

The hanger assembly of claim 1 wherein the nut is configured for use with a strut-type metal framing channel.

### Claim 3 (depends on 1)

The hanger assembly of claim 1 wherein the nut has a thickness that is less than the width of the slot.

### Claim 4 (depends on 1)

The hanger assembly of claim 1, wherein the threaded rod is a low carbon steel rod.

### Claim 5 (depends on 1)

The hanger assembly of claim 1, wherein the threaded rod is an all-thread rod.

### Claim 6 (depends on 1)

The hanger assembly of claim 1, further including a washer, the washer contacting the bottom of the associated framing.
