A cable tensioning system for mounting a vinyl sheet to a billboard frame, comprising a cable secured on a frame at one end and secured to a spring-loaded cable tensioning device at the other end. A plurality of cable guides are mounted at intervals around the frame, each of the cable guides having a channel adapted to receive the cable. Portions of the edges of a sheet are secured within a plurality of locking clips around the perimeter, each clip also having a channel to receive the cable. The sheet with the clips affixed is secured to the frame whereby cable travels through the channels in the locking clips and is guided around the perimeter of the frame by the channel guides and secured to the spring-loaded cable tensioning device. The spring-loaded cable tensioning device is deployed to tighten the cable around the frame and secure the sheet to the frame.
