Vinyl record albums are very heavy. I used 1x6 lumber for for the base of the shelves, so about a 5-inch thick stack of records would fit comfortably with some wiggle room so we can flip through the records. I fastened the display racks securely to wall studs with several long screws and washers to hold the weight.
Each 5-inch stack of records weighs about 15 lbs. Each rack holds four stacks for a total of 60 lbs of records. I made three racks, so that adds up to about 180 lbs of vinyl record albums. Wow!
Here is a close-up of the end of one rack so you can see how the pieces are joined together. If you would like to make these display racks, click here to download my PDF plan.
