RetroLOCK™ Overshot Assemblies & Options
Along with our high-performance EdgeLOCK overshot assembly, which features a unique edge lock mechanism that automatically locks the overshot lifting dogs in place, Di-Corp also offers the RetroLOCK series—our take on a trusted, traditional overshot locking system. The RetroLOCK overshot assembly is a simple, self-locking, and compatible drilling product designed to retrieve the inner tube assembly efficiently.
