Eye & Hook Turnbuckle Suitable For Permanent Tensioning Of Steel Structure Cables And Marine Rigging

OC Type Eye & Hook Turnbuckle is the most versatile and widely stocked open-body turnbuckle among all four mainstream turnbuckle configurations, strictly produced following DIN1480 industrial specification for global rigging market demand. The whole product consists of three core components: open forged main body, threaded stud with closed circular eye on one side, and threaded stud with forged open hook on the opposite side.

All load-bearing parts adopt hot die forging forming technology rather than casting processing, effectively avoiding internal sand holes, shrinkage cavities and brittle fracture defects that frequently appear on casted alternatives. Raw material selects high-quality carbon steel with stable mechanical property. Multiple surface treatment solutions can be supplied: electro-galvanizing for regular indoor and common outdoor scenarios, hot-dip galvanizing for coastal, humid and long-term outdoor working environment. For marine and corrosive chemical operating conditions, customized 304 and 316 stainless steel OC turnbuckles are also available for selection.

The unique eye-and-hook mixed terminal design makes this product stand out in practical application. The closed circular eye can be connected with shackles or anchor points for long-term fixed installation, providing reliable closed connection without accidental separation. The forged open hook enables direct hooking onto wire rope loops and connection fittings without additional pins, which greatly simplifies assembly work and allows rapid disassembly when maintenance or adjustment is required. By rotating the central open body equipped with bidirectional reverse threads, users can freely extend or shorten the overall length of the turnbuckle, realizing precise tension adjustment for cables, steel wires and tie rods without twisting the connected wire ropes.

We provide a full series of metric specifications covering M6 up to M42, each specification is permanently marked with clear working load limit on the main body for convenient inspection and identification by field operators. This turnbuckle has comprehensive application scenarios across multiple industries. It serves as the primary tension fitting for heavy goods transportation and container cargo lashing in logistics sector. In construction industry, it is commonly used for wire mesh fence tensioning, sunshade awning cable adjustment, advertising board support and temporary steel structure guy cables. Besides, it is widely applied for small vessel deck rigging, pipeline support fastening, stage temporary tension systems and agricultural facility cable tensioning.

Important Safety Warning (Must be displayed on product page)

This standard open-body DIN1480 OC turnbuckle is engineered only for static tensioning and cargo securing service. IT IS PROHIBITED TO USE FOR OVERHEAD LIFTING OPERATIONS. The open hook structure carries the risk of slipping off under sudden impact load or load reversal. For permanent heavy-duty tension projects with high safety requirements, customers are advised to choose Jaw & Jaw (UU) turnbuckles with closed clevis and pin locking structure.

During installation and service, users should regularly carry out visual inspection to check for permanent deformation, severe abrasion, cracks and surface corrosion. Do not weld, bend or modify the hook, eye and main body arbitrarily. Do not overload the marked working load limit.
