Excell ET-11171 Steel Desk Top Tape Dispenser is a high-quality steel desktop dispenser used for tape on a 3 inch diameter core. The maximum outside roll diameter the dispensers can hold is 5 inches so it works great for office supply tapes, film carton sealing packaging tapes, and paper masking tapes. The dispenser's serrated, anti-rust blade is used to cut the tape and there is a safety guard on the dispenser which can be manually pushed up to cover the blade. The dispenser's blade works well on cutting tape that is 3 mils thick and under. The dispenser has a weighted, padded foam base.
