Kryptonite Stronghold Above-Ground Anchor Review

Average Reviews:

(More customer reviews)The installation is not particularly hard, but it is time consuming. I wore out a cheap hammer drill that I had borrowed from a friend on the first hole, and ended up purchasing my own to finish the job - I used this: Makita HP1641K 5/8-Inch Hammer Drill Kit and it still took a few hours. I also wore out the masonry bits that came with the anchor and had to buy a second set. The anchor holes are pretty big - 5/8 inch diameter - so a cheap hammer drill may not be sufficient. Renting a drill is an option to consider.
A couple of other notes regarding installation: don't forget to wear ear protection! I was stupid and didn't, resulting in hearing impairment for the next 1-2 days. Also, carefully consider placement of the anchor - this seems obvious, but consider how you will be using it. I use it to lock up two bicycles inside my garage in conjunction with Kryptonite New York Fahgettaboutit 1415 Chain Bicycle Lock with New York Disc 5 Lock Chain Bicycle Lock, and I placed it fairly close (less than 6 inches) from a wall. I wish I had actually mounted it a little further from the wall, because to secure both bikes with the chain through the frames and front wheels, I end up having to reach underneath the bikes to lock/unlock them, which is cumbersome - it would have been much easier if the anchor was further from the wall. Lastly, make sure the holes are deep enough to accommodate the anchors before attempting to insert them - the fit is snug and they are difficult to remove if you find that you have to drill the hole deeper.
Otherwise, it works as advertised.
