Each year you take your time perfectly winding up your all your wires so that you can unwrap them tangle-free next time they're needed. Nonetheless, when the time comes to unwind them, the wires are tangled to what seems like an impossible task to unravel. With the Install N' Store Light Storage Reels you can keep your lights, wire, and extension cords tangle-free. The bag comes with 3 spools to wrap up your wire, along with 1 rain gutter/ladder hook to help you easily roll out your Christmas lights as you install them along your roof line. Depending on the wire type and/or light bulb type, each of the 3 spools can each store up to 150 ft. of extension cords, 125 ft. of mini lights, or 75 ft. of traditional Christmas lights.
