Ferrule Bootlace

6mm Green

Ferrules are a reinforced shaft that binds together wire strands into a small deformable metal tube, generally made out of tin plated copper. This short tube is placed over a section of stranded wire extending from stripped insulation, then compressed with a crimping tool to hold the strands together. Ferrules feature a flared portion which serves to guide the strands into the main crimped section and provide strain relief.

Ferrules come in a wide variety of different sizes, depending on the wire that you need to crimp, with color codes on the shoulder portion that indicate the size.
