The GBS Elettronica Jolly Line Open 2 is a replacement remote control that operates at 433.92 MHz and supports up to two independently programmable channels. It duplicates any fixed-code remote control on the same frequency, making it a direct substitute for lost or damaged originals.

The device uses a self-learning programming procedure that requires no tools or technical expertise. A protective door covers the keys, and the metallic construction provides durability in everyday use. The included 12 V – 27A battery means it is ready to program immediately out of the box.
