Panasonic KX-TGA740B Expansion Handset and Charger
Panasonic's KX-TGA740B expansion handset allows you to add a new handset and charger to your existing KX-TG7431B, KX-TG7432B, KX-TG7433B, or KX-TG7434B system (to a maximum of 6 total handsets). It has the same features and style of the handsets that come with those systems, and the charger takes up very little space (3" wide by 3.4" deep).
