Tire Restraining Devices (Cages) From Ken-Tool Meet Safety Standards for Higher Inflation Level

Akron, Ohio – (May 2, 2013) – Ken-Tool, the leader in tire service tools has 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. Ken-Tool is the first manufacturer to certify tire inflation restraining devices in its product line achieve this new level.

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 percent 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 is particularly pleased to achieve this new pressure level certification for its U.S.-built tire inflation cages, including those we’ve made in the past,” stated Rock Tyson, Vice President, Sales and Marketing for Ken-Tool. “This allows all of our customers servicing tires to know that Ken-Tool cages are safe for use with these new tire and wheel combinations.”

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