How to Build a Pet Agility Course

Attach the tee-pipe pairs to create one long line. Insert a 12-inch pipe into the tees on either end of the run and fit each with an elbow, a 24-inch pipe, and an end cap. Insert a 40-inch pipe fitted with an end cap into each of the six tees. Lay the entire row on its side on a flat surface to keep all the tee outlets parallel. Mark a line that crosses in between each tee and pipe between the uprights so that you can keep them lined up the right way when you put the screw in. Using a drill/driver, drill a hole at each connection, making sure the mark stays aligned. Secure these connections with 1-inch set screws.
