Thrust Bearings & Safety Lock - This patented design, found in Light and Heavy Duty Steel Shores, greatly reduces the amount of friction caused when adjustment to the nut is made when the shore is under load and significantly increases its jacking capability. Unlike the standard steel shore, thrust bearing shores are built as one complete unit to aid in uplift resistance and do not come apart. We have also added the Safety Lock set screw in the side of the nut. When tightened down, the adjustment nut locks in place for permanent or long term shoring applications.

*Load capacity includes a 2.5 to 1 factor of safety. 

*Do not lift more than 20,000 lbs.

*Steel Shores should be attached to a flat solid foundation and should not be subject to any lateral force. Heavy Duty Steel Shores should be used to support straight vertical loads only. We recommend tightening set screw in the side of the 4 hole nut with 6mm allen wrench prior to loading (unless lifting). Do not extend screw past advertised adjustment range.  Before construction begins it is recommended that you consult with certified engineer for approval of our products within your application.
