Opti-Seal Step-Down Connectors offer visual assurance to the installer thanks to a window made of clear cross-linked ionic polymer. These Step-Down Connectors will ensure error free crimping and terminating of different gauge wires therefore eliminating any guess work. Optimal viewing capabilities ensure correct crimping and centering. As a result, you prevent poor termination from wires stripped too short or not fully seated to connectors.
