Product Description
The 4128-6-2 is a nonconductive terminal cover designed to insulate and protect exposed electrical studs and lugs in aircraft wiring systems. This elastomeric cover shields SAE AS7928-style crimp terminals from accidental contact, preventing unintended electrical shorts in high-current applications like starter contactor circuits. Installation requires selecting the appropriate size to fit the stud, lug, and existing insulation, then sliding the cover over the connection per FAA AC 43.13-1B guidance.
Common on general aviation and commercial aircraft where exposed terminals pose safety risks during maintenance or operation.
