JunkYard Dog Industries is proud to announce the successful completion of third party testing of the ZSTRUT™. Following the same style of testing as performed on the XTEND™ model, the ZSTRUT™ was able to hold 11% additional force as compared to the XTEND™. Testing was performed at a certified laboratory under strict conditions. This third party verification of the rescue strut’s performance insures that rescuers using the JYD rescue struts can depend on their safety rating.
