Overview
Four of the 2857 captive screws are inserted into a CR720 or CR720XL chassis cover plate before it leaves the factory. These screws are used at the corners of the cover plate to secure it to the underlying chassis. The screws are also used to secure the side cover plate and the Control Module to the ENC7F and ENC7L Enclosures. Individual screws may be purchased to replace a lost or damaged screw.
