TrackPack Mounting System

Tubular ribbon has no edges to cut or injure, and is inherently slippery and smooth. This is the same material selected and used for many years by the Peregrine Fund for the attachment of harnesses in their migration studies.

Machined from high-strength Delrin plastic, the mounting plate features rounded and smooth edges with a gently curved shape to better match the shape of the back. UV-resistant Delrin is rated for 20 years in direct sunlight without becoming brittle or cracking.

Starting with 36 inches, or 18 inches per side, allows enough extra room on most Hawks and Falcons to have about 5-7 inches extra for manipulation, sizing decisions, and general handling.

Brass tubing is tapped with a thread to provide a better bite when crimped. It has been tested to around 25 pounds of holding strength.

The Micro size uses the tightest smallest ribbon and accommodates only a Micro sized spring. The Regular size accommodates all transmitters including the Micro. The XL or Eagle size uses 1/4 inch ribbon with a longer mounting plate, suitable for large Buteos as well.
