Carstens Kardex-Visitray Document Filing Systems are the ideal solution for organizing and protecting frequently-referenced documents in medical facilities, offices, restaurants, resorts and beyond. The 20-pocket model for 8.5" x 11" sheets features a protective plastic cover and 20 double-sided vinyl pockets, evenly tiered for easy browsing. Each vinyl pocket has a thin clamp on one end that can secure a sheet on either side of the pocket, leaving the face of your documents accessible for writing on. The vinyl pockets are anchored in place by metal rods to enable quick and frequent page turning without damaging your papers – ideal for standing up to rigorous use by multiple people. The tiered pockets are housed in a sturdy plastic frame that keeps the whole office filing system compact (only 1 3/16" thick). It's great for desktop use or it can be hung with Carstens Visitray wall mounts for unobtrusive, low-profile file storage. For over 130 years, Carstens has been the choice of the pros, setting the standard for quality and durability and functionality in products for healthcare facilities and beyond.
