## Abstract

A conduit stub-up assembly as disclosed herein comprises a conduit connector comprising a connector body including first and second openings for selectively receiving conduit end portions. The second opening has a threading element and is of a select diameter corresponding to a size of conduit end portions. A conduit stub-up form comprises an elongate tubular wall having a shoulder connected to a narrowed cylindrical neck closed at a distal end. The elongate tubular wall is of a diameter greater than the select diameter and the neck has a size to be removably received in the second opening and being engagable by the threading element.

## Claims

### Claim 1

A method of providing an in-slab conduit stub-up connection comprising:
coupling a first end of a conduit connector to an in-slab conduit;
coupling a tubular form with a second end of the conduit connector, the second end having a threading element, the tubular form extending above an intended slab grade;
pouring concrete to form a slab surrounding at least a portion of the in-slab conduit and the conduit connector, the tubular form extending above the slab; and
threadably removing the tubular form from the conduit connector.

### Claim 2 (depends on 1)

The method of claim 1, wherein the tubular form comprises an elongate tubular wall having a shoulder connected to a narrowed cylindrical neck closed at a distal end, the elongate tubular wall being of a diameter greater than the neck, the neck having a size to be removably received in the second end and being engagable by the treaded element.

### Claim 3 (depends on 1)

The method of claim 1, wherein the tubular form is of plastic construction and wherein coupling the tubular form with the second end of the conduit connector comprises inserting the form linearly into the second end and wherein threadably removing the tubular form from the conduit connector forms threads in the tubular form.

### Claim 4 (depends on 2)

The method of claim 2, wherein the neck comprises a threaded neck.

### Claim 5 (depends on 1)

The method of claim 1, wherein the tubular form is of one piece plastic construction having a generally smooth outer surface.

### Claim 6 (depends on 1)

The method of claim 1, wherein the tubular form is hollow.

### Claim 7 (depends on 1)

The method of claim 1, wherein the tubular form has a draft of about 1° to aid in removing the tubular form.
