Review on Sliding Door Window Aluminum Patio by Andy Tunes

Works GREAT on sash windows. Tools are not required. Easy to paste. stay safe Easily removed when the intention is temporary use. Just make sure you check the grinder track width before you buy. I thought all mine were "standard" (which have a fairly narrow gauge) until I tried them on windows I had installed with very wide indentations 7 years ago. We must look for an alternative to these two windows. But I am very happy with what I bought. And great for the price (which I paid anyway)
