The RS-250 Rotary Spider top cover and guides remain approximately 7 1/2 inches above the rig floor, 30 inch OD. Its unique design gives it the ability to run control lines along the tool string by incorporating the Frank’s safety interlock system. The spider can be used in rotaries with diameters as small as 27 1/2 inches, as well as in larger rotaries with the use of adapters. The rotary spider is suitable on casing, completion tubing, or drill pipe applications. Corrosion-resistant tubing can be run with Frank’s slips and inserts.
