TYPE 10 TURNBUCKLES
Elegant Design,
Exceptional Performance
From their clean lines to the use of the highest grade materials and
quality 昀椀nish, 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 pro昀椀le 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 昀椀ne 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 昀椀ttings 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 昀氀owing the full length of the thread. Threads
are UNF (Uni昀椀ed National Fine), short pitch threads for 昀椀ne adjustment and reduced
adjustment e昀昀ort.
Roll swage integrity
Swage 昀椀ttings 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 昀椀ttings complement the turnbuckles to permit
assembly of 昀椀nished 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.
