About Premiere's Couplings:

Whatever Your Application, Selecting The Proper Equipment For The Job Is Very Important. Proper Selection Along With Regular Inspection And Maintenance Will Help Keep Operating Costs Minimal While Providing Long Life To Each Component. To Determine Wear Limits, Premier Created Wear Gages That Help Judge The Useful Life Of Couplings And Drawbar Eyes. In Accordance With Premier And The Federal Motor Carrier Safety Regulations, These Were Designed To Identify Wear At The Critical Percentages Of 18% And 20%, By Measuring The Cross-section Of Coupling Hooks (Horn) And Drawbar Eye Loops.

Selecting The Right Equipment:

Each Premier Product Undergoes Extensive Design And Testing Prior To Being Introduced. Premier uses The Latest In Computer Aided Design And Analysis Software; As Well As Physical Destructive Tests.
