These are photos of trials of the above reel made by AK Reels. This is a very clever gadget and if you have the room to fit it we absolutely recommend it as we have the water hose version fitted to our mobile office and it works flawlessly. To extend simply pull out the entire length. Plug into van and power pole. To store just disconnect, jerk lightly and the cord retracts automatically. This system avoids cable damage. You wont see these in the shops just yet as the product is so new. More info from AK Reels - contact Wal McAnoy.
