Hinged with Spiral Nail Stop Collar
Eneroil Hinged Spiral Nail Stop can be used in both upset and non-upset casing to provide maximum clearance during rotation. It has a groove in the middle into which a spiral nail can be driven for improved grip on the casing. The broader band firmly grips the collar into position around the casing.
