I was tired of my Dumbbells being on the floor so with a $11 dollar investment, i was able to solve that problem. After a trip to Lowes i decided to use a 4′ stair tred from Lowe’s. I like the stair tred because it is thicker than a regular 1×12. WIth a few scrap 2×8’s from the neighborhood construction dumpster and a 2×4 as a support underneath, I have a functional dumbell rack. Like my other projects some Gorilla Glue and drywall screws holds it all together. DIY dumbbell rack.
