One GrooveMat for your Bin-e LP Storage unit. The GrooveMat is a thick Grooved Vinyl Mat that fits perfectly in the bottom of your Bin-e. Your records will be easier to browse. The Vinyl Grooves will hold your collection in place and prevent any movement. You can now fill your Bin-e half way and not worry about them sliding forward. Keeping your LPs vertical is the best way to store your collection. Excessive leaning will cause warping over time. The GrooveMat will allow you to maintain 100% vertical LP storage.
