Create-A-Space™ 透明上層隔板

Wasn't sure the divider would fit my existing column posts, but the included hardware went on without a fight. Now the top shelf actually holds small parts instead of everything sliding around.

Adding the divider turned my plain storage unit into a proper two-level organizer, and the see-thru panel means I can still spot things at a glance. The hardware lined up with the existing column posts without any drilling fuss.

The panel slipped right between the two column posts without any wobble, and the hardware lined up perfectly with the pre-drilled holes. I didn't bother with the stabilizer wings at first, but the upper deck feels solid enough that I might grab them anyway for heavier stuff.
