Elegant Design,
Exceptional Performance
From their clean lines to the use of the highest grade materials and quality
finish, Ronstan Type 10 turnbuckles are engineered to deliver performance
while enhancing the appearance of any yacht, or tensile project.
Type 10
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.
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.
Termination options
A full range of eye, fork and toggle fittings complement the turnbuckles to permit assembly
of finished rigging elements to suit virtually any application.
Calibrated turnbuckles
For accurate, repeatable settings of rig tension and precise adjustment, calibrated turnbuckle
models are available for wire sizes up to 8mm (5/16”); thread sizes 1/4”, 5/16”, 3/8”, 1/2” UNF.
