I’ve been trying to come up with a solution when I’m running to the grocery store and I have 2 kiddos with me. This divider with 4 hooks on one side and chest latches securing a 2 x 4 x 54 3/8” to a 2 x 8 x 54 3/8” (tapered down a 1/4” at the bottom) will keep things from sliding around! I used a textured black paint and also cut grab handles in the 2 x 8 using a 2” hole saw and a jig saw. Total cost was $46 and took about an hour of time without counting paint dry time. This also includes 4 additional hooks that I haven't (not sure that they are needed) attached yet. I am going to grab another chest latch tomorrow to add to the center of the other side to snug it together a little better. It will also make the unit a more solid, finished piece when attached.
