Replacement plastic strips for your 3Com NBX 1102, 2102, and 2101 phones.
Note: There are 2 types of plastic strips. The older 1102 phones had a soft plastic strip with a small tab in the upper left and lower left in which it would slide into a notch on the phone. The newer 1102, 2102, and 2101 phones use a hard plastic strip that has a tab at the bottom center and a pull-up tab on the top center in which this tab would snap into the phone.
