Twist-to-Lock PTO Cable Head – Secure Knob Variant Overview

This variant of our PTO cable series features a twist-to-lock knob designed for added control security in vibration-heavy environments such as construction vehicles or off-road applications.

Twist-to-Lock Feature:

After pulling to engage the PTO system, the operator can rotate the knob to lock it in position. This prevents accidental movement or disengagement due to:

• Equipment vibration

• Inadvertent bumping

• Continuous mechanical shock

Technical Overview:

• Knob Type: Twist-lock, black plastic with ergonomic grip

• Locking Mechanism: 90° twist holds position mechanically

• Available Threads: 1/4-28, 1/4-20, 5/16-18, 5/16-24

• Cable Compatibility: Standard push-pull conduit with steel innermember

• Mounting Support: Designed for Chelsea®, Muncie®, and similar PTO systems

This knob variant is best suited for applications where operator safety and positional integrity are critical.
For other control types (e.g., red pull-knob, engine stop integration), refer to our complete PTO cable product page.
