Saying that this retractable extension cord reel is well-built would be an understatement. The frame is virtually indestructible and VERY heavy. My wife was home when this item arrived and she couldn’t even move the box, let alone pick it up. I actually had to change the installation location I had chosen as the wooden beams were not substantial enough to confidently support both the weight and the force of pulling the cord out of the reel. As you can see in the attached photo, I had to go with a ceiling mount into a specially modified LAM beam that was previously installed to carry extreme loads (up to 14,000 pounds). As other reviews have mentioned, the sheer weight of this retractable reel makes an extra-secure installation imperative to avoid serious injury, especially if you choose a ceiling mount. Aside from having to put some extra thought and attention into the installation and location, this item is absolutely fantastic. I honestly can’t think of anything negative to say about this product with the possible exception of it being REALLY heavy, there is a typo in the directions so make sure you measure the distances between the holes in the mounting plate yourself, and, while the total length of this product (including the 5 foot cord containing the wall plug) is 101 feet, the extension cord itself is only 96 feet long. This shouldn’t be an issue for most people, but if you are buying this for a project where you need the actual extension cord to reach 100 feet from where you mounted the reel, you will be very disappointed as it will be 4 feet short. This is not an easy product to install so be prepared to need help with this installation as it is definitely a two-person job. I commend the writer of one review I read who provided detailed directions for installing this product by taking the entire real apart and then putting it back together again. This allows you just mount the plate easily but, due to the varying tension involved depending on how much cord is in the reel, you must be extremely careful when you disassemble and reassemble the reel. I was too nervous to go with the disassembly/assembly route and I also wanted to try to mount this reel myself as a one-person project. I have provided photos of the installation but I will briefly describe the process here. This procedure allows you to leave the entire reel intact and perform a ceiling installation by yourself but you will need to buy two extra mounting bolts. First, carefully measure the distances between the centers of the two mounting holes and two mounting slots. Mark those four positions on the surface you choose to hold the mount. Predrill all four holes, screw in the two bolts that will hold up the two slots in the mounting plate, leaving a gap of about 3/16 to 1/4 inch on each bolt. Screw the other two bolts that will hold up the two holes in the mounting plate in completely and then completely remove both of the bolts. Now, with the reel on the floor, unwind all of the cord and make sure that the reel locks in place. I discovered that the locking mechanism of the reel is very sensitive in this position so I would HIGHLY recommend clamping the cord around one of the rollers (see picture) to prevent the reel from retracting the cord unexpectedly. With the cord unwound, the reel, while still heavy, becomes light enough to be lifted to the ceiling by one person. If you slip the two mounting slots completely into the 3/16 gaps you left between the mounting surface and the two bolts, the entire reel should hold, wedged to the ceiling, on those two bolts. The weight of the reel is sufficient enough to hold it without slippage. You can then put the other two bolts through the two mounting holes and screw them back into the mounting surface. Once those two bolts are screwed back in enough to hold under pressure, the reel is secure and will not fall down. Simply finish tightening all four bolts, remove the clamp on the cord, and let the cord retract itself onto the reel until it is completely rewound. I hope this installation method proves useful to you. It worked great for me! In conclusion, the manufacturer spared no expense when they made this product. It even has four-way rollers around the cord’s exit point to ensure that the cord will never suffer any wear (see the attached photos and video). I wouldn’t be surprised if this cord reel not only outlives me, but that it will still be functional well into the next century. This is a must buy for anyone who needs a super-long, heavy-duty, retractable extension cord that will last a lifetime.
