Rather than use metal in its digital display mounts, Ergotron uses long fiber and wear compounds from RTP Co., Winona, Minn., (rtpcompany.com) to improve efficiency of its LX large display cart. Ergotron says RTP's materials improve performance at lower weights while minimizing cost.

An RTP 800 series glass reinforced and PTFE lubricated acetal compound provides high strength and wear resistant properties for a mechanism's cam. This strength lets the cam hold a load, while wear resistance properties help it move with the springs and cable. Pulleys that support cable movements are made with an RTP 800 series acetal with aramid fiber and PTFE. This compound provides wear resistance and low friction, and reduces noise.

Improvements over previous support bases for Ergotron carts were made by replacing metal with an RTP 200 Series nylon 6/6 long glass-fiber reinforced compound. In addition, brackets that hold glass shelves are also formulated with an RTP long fiber high-strength.
