My friends and I finally decided to build a backyard pvc rail. It was quite easy to build and only ended up costing around $50. This rail slides well and has been durable. If you are looking to upgrade your backyard park I recommend our design.
2 2x10 PVC Pipes
1. Cut your 4x6x8 into 17 inch pieces and cut your 2x4x12 into 3ft sections. The 17 inch pieces will be the supports or the part that gives the rail hieght.
2. Attach the 17 inch supports between the 2x10 pieces to form a ladder.
3. Add the PVC pipes to one side of the 2x10s.
4.Add the 3ft pieces onto the base of the rail.
*You can change the heights of the supports depending on how tall you want your rail to be
