Does anyone know where I can find Heating tape that has these same leads or know what they are called? It is meant to be plugged into the second picture attatched.
When searching for 1100 watt heating tape, a number of returns match almost exactly the image you've provided. A few of the manufacturers provide NEMA separable molded plugs and also offer bare leads. The bare leads would be useful in this case, as you can add your own 90° banana plugs.
To locate the correct plug, I used "right angle enclosed banana plug" as the search term. The image and source information came from Zoro online. I had better returns using shrouded in place of enclosed. Many sources. Be sure to check the current draw for the tape you'll use and the connector you'll select.
