This 90° 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-degrees) or rotated (180-degrees) - 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° Tape-to-Tape, Flex connector to create a 90-degee corner where two strands of tape meet, as well as flex to accommodate an additional change in direction.
