The EA , AD, SAD, FAD and ZAP covers are mainly available in yellow (labelled with a lightning flash) are used to cover the cross connect channel and screw holes of the terminal.
EA, AD & SAD covers are for the screw terminal range, where the FAD are for pressure spring and ZAD are for the tension spring range.
The BS 1 marker pen or the EMS labelling system can be used to label the white variants. The AD 4, is designed to cover four terminals of various sizes and is secured by two plastic screws.
