This shoe cover dispenser, approximately 16'' x 8 ½'', allows swift, easy, hands-free fitting of temporary shoe covers, greatly reducing the spread of soil and germs brought in on footwear. The shoe covers are ideal for moderate use in food preparation areas, medical facilities, show homes, anywhere requiring reduction of trafficked dirt. The AD1 comes with 110 #ADR2 included. The #ADR2 is our standard polyethylene shoe cover, and a heavier version #ADR3 is also available. Full instructions for fitting the shoe covers are included in the box, and there is a brief video to help you, see https://www.youtube.com/watch?v=Q8YkMgcYw-o . Shoes and boots should be dry before the covers are fitted. Don't locate the #AD1 in cold stores, because prolonged cold reduces the elasticity and effectiveness of the #ADR2/#ADR3 ankle band.
