Use US postal regulations and Martin Yale's new EX5100 Express Tabber to save both money and time when mailing. Applies one adhesive tab or wafer per pass to seal each mail piece, at up to 7,500 pieces per hour. Reliably handles open-ended mail without misfeeds, turning folded letters into ready-to-mail documents. This mail tabber adjusts to accept pieces from 5" to 12" wide, and the adjustable tab dispenser allows you to precisely control tab location. Accepts rolls of up to 5,000 tabs. Please note this unit does not handle clear tabs.
