Blind Box

At Kriloha Ltd., we supply Blind Boxes, robust wireline tools designed to tag or dress the top of stuck fish in preparation for fishing operations. A blind box is essentially a solid heavy-duty block lowered into the well to flatten, smooth, or locate the top of a fish. Constructed from forged alloy steel with precision-machined dimensions, Kriloha blind boxes are API/ISO compliant and suitable for HPHT, deviated, and horizontal wells. Applications include dressing rough or jagged fish tops to allow spear or overshot engagement, tagging obstructions to confirm depth, and aiding diagnostic fishing operations. Each blind box undergoes impact load testing, dimensional accuracy checks, and endurance verification, ensuring rugged dependability. As a supplier and facilitator, Kriloha Ltd. provides custom blind box sizes, heavy-duty tool string compatibility, and operator training, making our blind boxes the preferred choice for reliable fishing preparation worldwide.
