Shallow and tall BD storage units?

[blindcat87]

I currently have two storage units behind the door of my HT room. They are inexpensive pressboard shelves from Wally World but they have been quite adepuate until just recently when I started to run into their limitations because they are too short and have a non-adjustable middle shelf that leads to at least two shelves being too short to hold BDs or DVDs in a standard vertical row requiring me to use two horizontal rows that waste a good amount of space and cost me about a third, maybe even a half of the space on those shelves.

The reason I went with those shelves is that they were the only ones I could find that were shallow enough to fit behind the door and still allow it to open most of the way and that had a stabilizing board at the base in front of the units thin enough to allow the door to pass over them despite the carpet thickness.

So, I am looking for shelves that are that shallow, with thin stabilizing boards that are a lot taller and that either have non-adjustable shelves the right size for DVDs and BDs or adjustable shelves that hopefully will allow me to store movies in vertical rows on each shelf. I think the depth is an even 5.3" since movies fit almost exactly in them. If pressed solidly against the back of the shelf, there is basically a hirline of shelf out in front of the cases. This depth is perfect since it fits the cases and allows the door of the room to open almost all of the way. I don't care if the shelves are pressboard, plastic, wood or wire. Width isn't a big deal, if they are narrower I will just buy more. I think the current ones are between 24 and 30 inches. As for height, the taller the better, more shelves are good. I think the current ones are around 48 inches.

I've looked locally, and can't find anything that will work at any of the limited sources for such things here. I would love to find something at Amazon since I am a Prime member, but need them enough to pay shipping if I can find something elsewhere. I've tried searching at Amazon and other stores, but most sites I've looked at depend on you checking out the images to see if you have found what you are looking for and that doesn't help me since I can't see the images. I've tried searching by experimenting with entering different measurement groupings into the sites' search fields but that never works since they all use different formats and don't seem to be set up to display based on measurement searches. So, any help would be appreciated.Right now I have my entire BD collection piled in four stacks on top of these two units and the arrangement gets more precarious every week. One stumble at the wrong moment and I am going to have nearly 500 Blu-rays falling down on my head. If I can get a few more shelves worth of storage and rearrange some other things I can fit everything properly into shelves and have some room to grow again. I just have to find shelving units that will fit the bill.

TIA,
