Among the truckload of hand-me-down baby gear we received was an E and I Bungee Baby Bouncer. It has a huge pincer on top to latch securely over most standard door frames. Therein lies the problem. Nothing in my DIY house is standard and the pincers do not open wide enough to fit around my custom door trim. Rather than deny my baby the fun of bungeeing, I removed the pincers and attached the whole thing directly to the floor joist above me, using easily obtainable items from hardware or outdoor specialty stores.

What You Need

• 1 Bungee Baby Bouncer or equivalent
• 1 load-rated carabiner (if not already included with the jumper)
• 1 Swing Hook–very important to get something rated for vertical loads
• 1 length of nylon webbing (4′ should be plenty)
• masking tape
• long screwdriver

• drill with a bit slightly narrower than the diameter of the hook
• stud finder


1. Remove the pincers from the jumper. This was as simple as slipping it off the carabiner in my case.

2. Use the stud finder to locate a joist. If your stud finder does not indicate the center, mark both outer edges of the joist and make your mark in the middle. Getting the center is important due to the size of the hook.

3. Hold up the threaded end of the hook next to the drill bit. Put a piece of tape around the drill bit to serve as a depth gauge.

4. Drill hole into joist. Screw hook into joist, using the screwdriver for leverage.

5. Estimate the length needed and tie the webbing into a loop using a water knot. Hook one end of the loop onto the swing hook. Attach the jumper to the other end using the carabiner.

6. Adjust the height of the webbing loop by tying a simple overhand knot along its length to make it shorter. The height adjustment feature on the jumper should take care of the rest.

Additional Notes:
Carabiners and webbing can be found at EMS, REI or any similar local stores that carry rock climbing gear. Suitable materials can also be found at any hardware/building supply store–just be sure to verify the load limits for weight. I used climbing gear because I had it at hand, and I know it is rated far beyond what I need it for in this situation.
