*Make adjustments to the height of the Mini Jack by turning the turning wheel. A 3/4" round rod can be used for extra leverage (MJ-TB12). Top plate will swivel independently from the screw.
*Mini Jacks should be attached to a flat solid foundation and should not be subject to any lateral force. Mini Jacks 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). Before construction begins it is recommended that you consult with certified engineer for approval of our products within your application. Do not extend screw past advertised adjustment range. Do not exceed max safe load capacity.
