2.1.1 5-card Shelf, model 751112/1
The 5-card Shelf, model 751112/1, accommodates Teleline plug-in cards. The
shelf is molded from specially treated polyurethane, making it lightweight and
flame retardant of high dielectric strength. The polyurethane body limits the
possibility of many kinds of infiltration while providing reliable isolation from
external ground potentials.
