Attaching wood to pipes is a challenge that many do-it-yourself carpenters run into when making alterations to home framing. Plumbing runs through the walls and typically intersects with wood in one of two ways. Either the pipe runs through a hole in the wood, or the pipe is mounted to the face of the wood with a metal strap. Both solutions serve their purpose and are simple to implement. When creating a "pass through" for pipes, make sure to keep it as snug to the pipe as possible.

Pass Through

Step 1

Measure the stud, or other framing member, to determine where the pipe will intersect with the wood. Mark the spot. Measure the thickness of the pipe and use a rafter square to mark the stud where the top and bottom of the pipe will be. Draw a line from each mark to the center of the stud.

Step 2

Cut along the lines with a jig saw, cutting a round ending between the two lines in the center of the stud. Cut a piece of 2-by-4 to 24 inches long with a circular saw. Mark an identical notch on this board and cut it out in the same way.

Step 3

Fit the pipe into the stud and fit the 24-inch piece over the pipe, aligning it with the stud, to cover the open edge of the board. Drive two 3-inch treated deck screws through the "scab" piece into the stud, one above the pipe and one below.

Pipe Strap

Step 1

Mark the height of the position of the pipe on the board at the top and bottom of the pipe.

Step 2

Wrap a piece of perforated pipe strap around the pipe, and cut it to length with tin snips, with two holes slack on each end of the strap.

Step 3

Drive one 1 5/8 inch treated deck screw through one hole at one end of the pipe strap so that the strap is just below the pipe position. Fit the pipe against the stud and wrap the strap up around the pipe and back to the stud, pulling the pipe to the stud. Drive one 1 5/8 inch treated deck screw through the strap above the pipe to lock it in place.
