Vinyl Storage Options

It is not that difficult to make your own. There is a picture in my virtual system with some I made from 1" finished plywood. The L-shape makes it extremely stable. Just make sure that the horizontal components are continuous and the vertical slots are in sections, except end-pieces. 

If you want longer sections, go with hardwood. I made a second unit built into a closet from 1" red oak with about 3 foot sections. Mechanical stability of hardwood is MUCH higher than plywood or MDF (used in Ikea etc. furniture). With fewer vertical separators, you get more storage space per linear foot. There is zero flex on the 3 foot sections even fully loaded with records.

The only things you need is a track saw (or table saw) and a router. Some glue, maybe either screws or dowels. Done.

@drlou77 I’d say 60-70 in each cube. 

Alphabetical, without the need to keep moving them around: I limit myself to 1 in/1 out, OR, even better 1 in/2 out and limited myself to 18 lf total (actually 17lf lps + 12 dividers/6/row). roughly 8 to an inch max, best to leave some space 

2 rows 9 feet long at easy height, one just above, 1 just below standing eyeball height, no bending, no reaching, 

I have alphabet dividers,

I installed 8lf of strip light overhead, close so you don’t make a shadow.

note: mine are hardwood library shelves I inherited with recessed metal tracks for thin adjustable dividers. I put them on top of the case’s shelves, and they are only 11" deep, so you can get them in/out more easily

One way to prevent sag is to limit the width to 30" wide case, so the shelf is only +/- 28" long

I much prefer record store style display and access of my collection. I use DIY shelf. See system under details.

However, this is a commercial product which looks great.

You’d need 2-3 units. They sell metal or wood versions in different sizes.

OP,

btw, this crowd, many have very large collections, I had 2500, inherited 4000, sold or gave away over 2000, and still weeding, I find I have a lot I play once and will never play again, which is why I say 1 in/ 2 out.
