If you work with alarm systems, access control, power supplies, A/V, HVAC, or any other industry that requires you to put a stranded wire into a terminal block, these ferrules will be your new best friend. For whatever reason, ferrules seem to have completely passed over our industry. Most of the customers we ask have never heard about these glorious little buggers and how they simplify your installs. So now we are on a mission to get them into all our customers hands!
Unless it is your first day on the job, chances are you've experienced hours of troubleshooting an issue that was caused by a single copper braid crossing into the wrong position on your terminal block. If you are really serious, you may even be tinning your wires with a soldering iron to avoid this exact thing. Another frustrating issue many experience is the entire wire coming out of the terminal blocks.
Ferrules eliminate the above two issues by containing the braid, and giving the terminal block something substantial to grip when tightening the screw down. The surrounding jacket on the ferrule is thin, so it barely changes the size of your wire. If saving you time and frustration wasn't enough, they also make your installs look sharp! The little plastic collar butts perfectly up to the terminal block giving a consistent and professional looking job!
These Ferrules require a specific tool for crimping.
