Product Overview

All Ellis Stealth Lifting Shores now come with the 4 lug lifting nut. Used the 3/4" Diameter Steel Adjustment Rod to lift loads up to 20,000 lbs.

The patented Ellis Thrust Bearings on the Stealth Lifting Shores enable these shores to lift up to 10x the amount of load compared to the Light Duty Steel Shores (w/o bearings).   Adjustable structural support column for temporary or permanent support with a patented nut housing tiny thrust bearings to allow for easier adjustment under load and jacking weight with significantly less force.  Add any length 3/4" Diameter Steel Adjustment Rod for extra leverage and lift up to 20,000 lbs.

In the product animation below the Ellis Stealth Shore lifts a sagging header beam back into place.  The locking set screw secures the nut to the screw to prevent any further adjustment.  Then the wall is sealed with drywall.  

The 3-1/2" x 3-1/2" top plate is attached with a clevis pin and interchangeable with different shapes and sizes. Click here to see a few of the different tops to choose from: STEEL SHORE TOPS.

*All Load Capacities include a 2.5 to 1 Factor of Safety.

Shop Drawings:

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