Patented by Ellis Manufacturing Company Inc. in the 1950's, the Ellis Shoring System is simply designed to bring lumber and steel accessories together to quickly and easily create an adjustable slab shoring system. The Ellis Shoring System is the most affordable and most versatile shoring system on the market. The Ellis Clamp is designed with a solid steel rectangular collar and two heavy duty malleable castings, which are grooved on the flat surface for firm gripping on lumber. Abuse will not break or distort, making the clamp durable enough to use hundreds of times and its cost per use 'pennies'. The Ellis Clamp is available in eight sizes to fit most nominal lumber sizes as shown in the load chart below. Lean more on EllisManufacturing.com
