Aluminum Tiller Extension
The rigid anodized body of this tiller extension transmits subtle boat and rudder 
movements, allowing the skipper to steer by the feel of the helm. The simple 
and lightweight design has no unnecessary frills—every aspect 
contributes to its strength, stiffness, or comfort. The universal joint and nonslip 
foam grip are UV-protected and perfect for full dagger-grip and 
fingertip steering.
Nonslip foam rubber grip.
Universal joint rotates 360°.
Base cover snaps off to remove 
tiller extension.
*Fasteners not included
Halyard Tensioners
Designed for rope or wire halyards on large cruisers, the Harken halyard 
tensioner locks halyards at full hoist and frees your halyard winch for 
other functions.
The one-piece aluminum car body is Hard Lube-anodized for durability. 
Track is extruded from 6061-T6 aluminum and hardcoat-anodized for 
a hard, long-lasting surface.
Choose the 40 mm version in single-pin, double-pin, or triple-pin 
configurations based on required working load. 32 mm version available 
in single-pin only. Custom cars can be designed to handle higher loads. 
To lock pin in up position, pull the 
handle up with a lanyard or by hand 
and twist 90 degrees.
