Holders

Portage Knife is a leading supplier of pneumatic score knife holders for the converting industry. We have thousands of holders in stock, ready to ship. Our pneumatic knife holders are interchangeable with units that are currently in use and are available in a wide range of widths, such as 3/8”, 1/2 “, 10 mm, and 12 mm. Holders feature precision ground spacers and side plates, tempered steel forks, and our air hoses are braid reinforced to eliminate those pesky line stoppages from failed hoses. We also have quick disconnect air couplers and our holders accommodate either 19 mm or 22 mm bearings. We also offer a wide variety of holder accessories and replacement parts such as standard air cylinders, couplers, flexible hoses, bearings, lube arms, custom air cylinders and axles needed for holder service.
