Our products include wall scratchers, stop collars, wall wipers, rigid centralizers, cement baskets and imperial bow centralizers. Our reciprocating scratchers are used for preparing the wellbore for cement bonding.

The cable and bristles also act as steel reinforcement in the cement column. These scratchers function primarily during casing reciprocating.
