The SMJ 15m 1 Way Ball Cable Reel is a safer cable reel than the normal extension reel, due to its zero tangle technology. Its safety features include feeding cable using innovative slip ring technology, as you work it folllows, its plugs can't be removed while in use, and it doesn't fall over when in use. Tough, strong and resilient, the folding handle also makes it easy to wind the cable back onto the reel. This is a great new product for 2010.
