TYPE 10 TURNBUCKLES
Type 10 closed body turnbuckles have a sleek, modern profile with no sharp edges. They are easily adjusted by turning the unique adjustment nut, which is free to rotate within the sleeve on the turnbuckle body, and are secured with a quick turn on the locking nut. A sight hole is provided in the body to verify adequate thread engagement. With fine thread and single end adjustment, Type 10 turnbuckles are much easier to adjust than conventional turnbuckles, and the use of dissimilar but compatible metals for the threaded components avoids the risk of thread seizure. Toggles are designed with full lateral articulation for easy installation and connection compatibility.
Calibrated Turnbuckles - For accurate, repeatable settings of rig tension and precise adjustment, calibrated turnbuckles are available for wire sizes up to 6mm (1/4”).

Fine, Rolled Threads
Ronstan rigging fittings have rolled threads for maximum strength and reliability – unlike cut threads, the stainless steel bar is formed up and down to create a thread with the grain remaining unbroken and flowing the full length of the thread. Threads are UNF (Unified National Fine), short pitch threads for fine adjustment and reduced adjustment effort.
Roll Swage Integrity
Swage fittings suit industry-standard roll swaging presses and dimensions are derived from the original ‘Milspec’ for maximum integrity. They are suitable for use with modern and traditional wire constructions, including 1x19, 7x19 and compact strand.
A full range of eye, fork and toggle fittings complement the turnbuckles to permit assembly of finished rigging elements to suit virtually any application.
OPEN BODY TURNBUCKLES
Ultimate Quality, Superior Adjustment Performance
Ronstan open body turnbuckles are made from polished chrome plated high grade brass bodies with grade 316 stainless steel end fittings. This combination of materials not only avoids the risk of excessive thread wear or seizure under load, but also provides the considerable advantage of easier adjustment.
As shown on the accompanying graph, for a given level of torque, up to 47% more tension can be achieved with the Ronstan brass body turnbuckle than with competitors bronze body turnbuckles, or up to 71% more than an equivalent stainless steel body turnbuckle. Conversely, for a given required rig tension the torque required to adjust a competitors bronze or stainless steel body turnbuckle is up to 40% or 75% more respectively than that of the Ronstan brass body turnbuckle.
After tensioning, cross-drilled ends in the threaded terminals enable the use of split-pins to lock and secure the adjustment. For easy thread identification an etched “R” identifies the right-hand threaded end of the body. As with all Ronstan turnbuckles, toggles are designed with full universal movement for easy installation and connection and allow the assembled cable to move where the structure is subject to wind loads or vibration.Toggle & Swage, Imperial Wire Toggle & Swage, Metric Wire Toggle & Toggle, Metric Wire Open Body Turnbuckle Bodies
