This 90 deg tape-to-tape, flex connector accessory is one of 8 patent pending connectors for the 8T series of led tape light. Its unique inner workings allow it to install with the tape straight on (0 deg) or rotated (180 deg) - regardless of the tape polarity. So, the connector accessory can easily push into the base on the 8T tape without having to check polarity. Use this 90 deg tape-to-tape, flex connector to create a 90 deg corner where two strands of tape meet, as well as flex to accommodate an additional change in direction.
