WM3 combines the best features of the WM1 and WM2. Like the WM1, it closes completely for a clean look. Like the WM2, installation and changing wires is super simple. Like both, WM3 is designed for easy access and total concealment of wires. However, unlike either, the WM3's front panel snaps open and shut, featuring an "invisible hinge". Serrated edges protect against fingerprints. Sold in one foot lengths up to six feet.
