Strength Testing of MaxiGrip and U-MaxiGrip Closures

MaxiGrip and U-MaxiGrip closures have been battle-tested by the U.S. military, putting in many years of dependable, reliable service for various applications. In many situations it was the strength of our closures that sealed the deal for the military's incorporation of our heavy-duty zippers. 

Ensure Performance

To make sure you can rely on the strength of our closures in your products, we provide general pull strength ranges for MaxiGrip and U-MaxiGrip profiles. Be sure to consult with our sales representatives about your product's unique specifications. Pull strength varies with materials, durometer, and fullness of track teeth. We ask for your requirements to determine feasibility.

The figures published on this website are based on testing done on an Instron model 3343 based on 1 inch sample at 20 inches of travel per minute with a 100 pound load cell.
