Ken-Tool announced the company’s line of 2- to 7-bar tire inflation restraining devices (cages) are tested and now certified to address higher, 130-psi inflation pressure levels.  

This new pressure level certification was prompted by the introduction of the 455/55R22.5 load range M truck tire, which is rated up to 130-psi inflation pressure. This tire and wheel configuration are growing in popularity for drive and trailer axles, replacing dual wheel/tire combinations.

The Occupational Safety and Health Administration’s O.S.H.A. Standard No. 29 CFR Part 1910.177 requires that inflation restraining devices contain 150% of a tire’s rated inflation pressure during a failure.  To verify the ability of the cage to absorb the energy released during failure, Ken-Tool tested a truck tire on a multi-piece wheel at 195-psi. 

Ken-Tool has posted a video to YouTube, which demonstrates the testing process. 

The company is printing new warning labels in English and Spanish to reflect this change for its new and existing cages.

Ken-Tool products are available through tire industry supply distributors worldwide.
