When you need directional control of your light, this grid system does the trick. It velcros easily to the front of our LED blankets, making adjustment quick and easy. All SnapGrids for our blankets are custom manufactured by RagPlace. The built-in stainless steel snap frame allows for fast set-up without the hassles of sagging when using your blanket in a horizontal position. Each Snapgrid® is manufactured using a specially developed robust fabric which keeps the grids stable. All strips are precisely sewn to the highest quality standard.
