Abstract: A plug-in surge protector having an improved handle for facilitating and isolating the removal of an individual protector from a protector panel without interfering with adjacent protectors. The plug-in protector comprises a body having a front end and a rear end. Extending from the rear end of the body are terminals for plugging into sockets on a protector panel. Extending from the front end of the body is a handle having a reduced width and concave upper and lower surfaces. On the concave surfaces are horizontal teeth running across the width of the handle. It is preferable that the teeth are tilted towards the rear end of the body and against the direction of removal of the protector from the panel. The reduced width of the handle allows the removal of a single protector without touching or interfering with adjacent protectors plugged into the panel. The teeth on the handle increases the frictional surface area to facilitate removal of the protector from the panel.

Abstract: A network interface unit is disclosed having two layers of equipment and a hinged arrangement that allows the layers of the equipment to be swung out away from each other to facilitate maintenance and to decrease wiring density, while at the same time also providing side expansion capabilities of the network interface unit.
