Used this to extend the cable from the frame when I replaced the stem mounted Junction A for the neater bar end one. Looks very neat

Reviews
Upgrading my Ultegra 6870 Di2 to the new bar end junction box required some new wires, and I used this junction to connect to the downtube wire. I was small enough to fit inside the bars through the existing cable opening without modifying the hole... just what I wanted. Bike has much cleaner look now...

Shifting the way the world rides.
From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
