A step towards greater environmental awareness. The Q-Doc 515 Circular document holder introduces a sustainable version of the acrylic product. All functions of the Q-Doc 515 remain intact. New is the PET felt material, which is made from recycled plastic bottles. By reusing plastic bottles, we help reduce plastic waste in the ocean and on land. Like the conventional Q-Doc 515, this document holder is also adjustable in various heights. You can choose from four different heights to position your documents at the right viewing angle. Working with a document holder helps prevent physical discomfort, as it allows you to keep the documents directly in front of you (between the keyboard and the screen), eliminating the need to turn your head.
