DESCRIPTION

The Double Breakout Clamps have an adjustable internal diameter to accommodate both drill rods and larger casings. The ID can be further reduced to 0.75" (19 mm) with optional ' long jaw-blocks'. Equipped with a top set of swivelling hydraulic clamps for breakout actions and a fixed set of bottom clamps for gripping. The jaw-blocks have replaceable hardened steel teeth or 'jaw inserts' to seurely hold casings and rods.

The distance between the top and bottom set of clamps is adjustable for various types of drill rod couplings. The slew ring is a bolt together assembly for easy maintenance. The Double Breakout Clamps are specifically designed for rope thread casings to allow thread float.
