I got a triple monitor support, only used it for 2 monitors, in a few hours it made an indentation on the desk, I'm considering buying some flat rigid material to be placed below and over the desk so the pressure is distributed more evenly, current clamp surface is 63CM below and around 67cm over, clamp opens around 8.5CM and desk is around 4CM thickWhich material is best? plywood? real wood? steel? Around which measures it should be? Should I place it both below and under? via /r/DIY http://ift.tt/2hhb7Dr
