Super Damper Harmonic Dampers

ATI's Super Damper for the Mini Cooper standard and "S" model is a direct replacement for the stock OEM damper from 2001 through 2006. The heart of this unit features ATI's "damper within a damper" design that has put ATI ahead of the rest. The outer shell retains the OEM 6-rib serpentine belt locations and includes laser-etched timing marks.

Features

Great for shed organizing
Size: 4.5", Style: Open, Size: 4.5", Style: Open
We recently upgraded to a conex/shipping container/metal shed and needed a way to organize all of our yard tools. These work great, the weight holds a lot of items, could be a little longer but we were impressed with them holding everything for over a month now and not moving.

Good product. Know the limits.
Size: 6 Inch, Style: Open
These are very nice. Sure beats drilling holes in your steel. However, 45lb is a stretch. Will easily hold 25lbs. However 35+ is a stretch, especially if your walls shift a little due to be close to a door. Will definitely order more, just important to understand the limits. Thanks.

Finally, a product that meets all of its advertised claims!
It seems to me like this product is always out of stock. Of the ones I have received and been able to use. They work as advertised and hold an incredible amount of weight. It is very easy to put them on and off, but once they are latched down, you could not remove them by hand without bending the hooks I would like to have a few more boxes to use in my steel building.

Magnet hooks you need!
Size: 4.5", Style: Open
I have been using these all over our shop and helps keep chords, tools and other items off the floor and more organized. I like the ease of the magnet, and it looks like. Built to last. I wish they were not so expensive.
