Besides 'regular' bootlace ferrules, you'll also find 'double' bootlace ferrules in our range. These bootlace ferrules, also called 'TWIN bootlace ferrules', are comparable to the normal variant, but are suitable for use with two cables.
What is a twin bootlace ferrule?
A twin bootlace ferrule is a copper sleeve with a wide insulation collar that allows two wires to be connected and secured simultaneously. They have a single sleeve and a plastic collar, which helps with positioning and protecting wires.
How does a double bootlace ferrule work?
In principle, a double bootlace ferrule works the same way as a 'normal' bootlace ferrule. The only difference is that you perform the steps with two cables, and then secure them simultaneously in the bootlace ferrule by crimping it.
Follow these steps to properly connect a cable to a bootlace ferrule:
- First, strip the cable that you want to connect to, for example, an installation.
- Then, place the cable with the exposed wires in the bootlace ferrule. Make sure that the wires will make contact with the copper tube in the bootlace ferrule when you crimp the bootlace ferrule with pliers.
- Finally, crimp the bootlace ferrule by pressing it in with pliers on the copper part.
Why do you use double/twin bootlace ferrules?
You use double bootlace ferrules mainly to achieve a better electrical connection; because the wires are pressed together, you prevent loose strands and improve conductivity. Additionally, they make connecting easier, because two wires can be neatly secured together in a terminal or screw connection. Using double bootlace ferrules also increases safety, since the wires are firmly bundled and the chance of short circuits or loose connections becomes smaller.
What do you use twin bootlace ferrules for?
Double bootlace ferrules are used, among other things, in switch cabinets, control panels, or in distribution installations. They are used to connect two wires into one connector.
