Breaker Panel 4x6 Directory Card Frame
A slide-in frame that holds a standard 4x6 in (101.6 x 152.4 mm) index card as your circuit directory on the inside of a breaker panel door, so the list stops tearing and falling out when the door swings. The card drops in from the top and sits under two 45° wedge lips, so the frame prints with no supports. Mount it with VHB tape on the flat back, or put M3 or #6 sheet-metal screws through the two 3.4 mm ear holes. The frame is 133 x 157 x 6 mm.
