The RIGGER ENGINEERING double slip version of the plain hanger is for extra heavy liners, between 80,000 pounds and 250,000 pounds. An extra row of slips allows for greater surface area with which to support the liner. If the liner is to be cemented, ports located below the hanger body allow for fluid circulation.

Like the single slip liner hanger the double slip shares the same unique design features. These include a short, streamlined body with few parts which can be run through dog legs and high-angle holes to set easily and securely. The fully recessed slip design features a true radius between the slip and the pocket. This allows the entire weight of the liner to be spread evenly over the entire contact area of the slip and the pocket. Each slip operates independently, further assisting in spreading the load evenly and allowing the hanger to work even in the unlikely event that a slip were to become jammed. Finally, with no exposed parts, it is virtually impossible to set the hanger prematurely or hang up while tripping into the hole.
