Keep students and employees protected with this Desktop Shield. The three sides of see-thru acrylic provide maximum safety and visibility and the 23.5” height is perfect for taller students or adults. The front panel features an 11” wide x .5” high opening at the bottom to slide papers and other small items back and forth. The hook cutouts on the side panels easily slide into slots on the front panel for quick assembly and the included four fasteners have adhesive bottoms to keep shields in place and prevent them from sliding. The side panels can be splayed out to the sides to an opening of approximately 27˝" to give children more room if desired. No tools needed for assembly. Fasteners are not reusable and additional fasteners can be purchased separately. Warning - Adult Assembly Required.
