RS PRO Insulated Crimp Bootlace Ferrule, 27mm Pin Length, 16.7mm Pin Diameter, 4/0mm² Wire Size, Blue

Looking for bootlace ferrules to complete a professional install, then consider the RS PRO range of crimp bootlace ferrules designed for clean termination of cable wire conductors to ensure the best possible electrical connection. RS PRO crimp bootlace ferrules are colour coded, available in multiple sizes and a most for any electrical engineer or DIY enthusiasts who pride themselves on completing a job to a high professional standard.

A bootlace ferrule is a metal tube or ferrule with a moulded colour-coded insulating collar made from nylon. The ferrule is slipped over the end of a multi-stranded cable wire, crimped, and then inserted into a screw or spring clamp connection.

When the end of a multi-stranded wire is stripped and placed directly under a screw terminal the strands of the wire will naturally fan out under the pressure of the screw. Some strands will go astray. This reduces the quality of the electrical connection and can also result in electrical shorts. When a bootlace ferrule is used, the insulated funnel with its flared design captures all the strands. These strands are then crimped together in the ferrule tube. The crimped ferrule is then inserted into the terminal to create an electrical connection.
