I made this out of 3/4 flooring plywood sheet that cost $35. So $50 all completed and sanded smooth and glued solid like a tank is a great deal. These go for over $100 online. I just need to clean up my garage so my wife can park her car in there. Honest! She’s mad at me. It measures 30” x 24” x 20”. If you’ve never used a jump box you don’t know what you are missing. If you have you know how essential these are for good leg explosions. I workout at a gym now so don’t need this. It is solid like a tank. Weighs a ton. I built it with internal 2x4 cross braces so when you jump on it there is NO flex. Professional grade. Call Or text Joe.
