(1 ) GrooveMat for your LPBIN3 LP Storage Cabinet.
You will need two mats to cover the top bins and one mat to cover the bottom bin (if using the bottom shelf adapter). .
Each Groovemat is 27" X 13" and the grooves run horizontal to the LPBIN2.
The GrooveMat is a thick Grooved Vinyl Mat that fits perfectly in the bottom of your LPBIN2. Your records will be easier to browse. The Vinyl Grooves will hold your collection in place and prevent any movement. You can now fill rows 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.
