MIP Heavy Duty Feedwheel Steel Strap tensioners allow operators to bring strap to desired tension with minimal interruption, effort and strap waste. Most tensioners have a base which goes under the strapping and rests on the flat surface of the object being strapped. The feedwheel tensioner has a serrated feedwheel which engages the strapping firmly. There is no limit to the amount of stack it can pull out of the strap. Fast and easy to use, it requires the use of painted and waxed strapping. For smaller or irregular bundles, a push-type tensioner, which has no base under the strap, is recommended. The MIP-1400 Specs: Strap Gauge Range (.025 to .031), Strap Width Range (3/4″ to 1-1/4″).
