Specification

Information

Body: Aluminum, black anodized
Lever: Aluminum, yellow anodized

Unlike thrust bolts or clamping screws, GN 704 quick release set collars generate locking force on the shaft via a cam lever.
This quick release design allows the collars to be set or adjusted rapidly and without tools.
The aluminum design results in low mass inertia values.
