Barrel pin tapers allow  ±4° articulation. Larger angles are available upon request
"02"versions for -76 and larger incorporate new, larger pin sizes.

Barrel Pin and chain plate recommendationS

The barrel pins are based on various very high strength materials.  Consult Navtec Engineering for pin material requirements. The pins must meet Navtec's standard barrel pin design parameters, including the radius specified at the end of the barrel geometry.

C890 Toggle Turnbuckle


Originally part of Navtec’s Grand Prix range, these turnbuckles are becoming more popular in every boat range. High-strength, light weight materials ensure performance without a weight penalty. Closed-body design means no cover is needed to protect today’s costly sheets and lines. Calibrated for accurate tuning. Available in marine eye, barrel pin, and toggle versions.


C560 Marine Eye Turnbuckle


Marine eye version of the C550 turnbuckle. Can be used with a reversed J100 toggle on female chainplates for articulation.



Turnbuckles for rod rigging


Turnbuckles are a critical part of Navtec’s rod rigging systems. They are designed to complement Navtec rod design and are made from 316 Stainless Steel for strength and corrosion resistance. Like all Navtec rod rigging system components, our terminals are polished to a gleaming finish to complete the Navtec look.
