The Shingle Speed Tab is an excellent improvement over the original shingle tab. This clip is designed to work seamlessly with smaller mini lights, as well as c7 and c9 cords. Its compatibility with a wide range of lights and cords makes it a versatile choice for anyone looking to add Christmas lights to their home or business. The Speed Shingle Tab is easy to install and ensures that your lights will stay in place, even in harsh weather conditions. Use with flat roof adapters for flat roof installation.
