“I got four of these to put a car tent on a new asphalt driveway. After seeing how large the ends are, I didn't think you would be able to hammer, or sledgehammer, these through ~3" of asphalt. I was right, you cannot even get them to start to go though.. I used a couple of carbide tipped masonary drills to make a hole almost as large as the end (enlarging to about 1.5" wide where the cable is attached, plus a long 3/4" OD drill to drill about 13-14" deep. Even then it was hard to hammer through the asphalt and into the packed driveway.
The bar was mushroomed quite a bit after the 4th one. The last one hit a stone about 4" deep and I left this as is. I drove the other three down until about 8-10" of cable was left out(leave enough to wrap around the driving rod), and pulled up on them. Then poured Quickrete Anchoring mix into each hole and this dried quickly (mix 2-3 times the 1:5 mix they say to do, it will not mix at 1:5). After doing this, they seem solid.”

“I Installed these last week. They are easy to install and very secure. Shelter logic initially sent a set that did not include the clamps. I contacted them and they sent a new set right away. Excellent customer service.”
We are glad to see that you are pleased with your Anchors! Thank you for taking the time to share your thoughts and for choosing Shelterlogic!, Customer Service
“I bought 2 sets of these to hold my 20x22 shelter logic canopy. Per the instructions I drove the anchors down, wrapped the cable around the driving rod and pulled up to set the anchor. 4 of the cables pulled right out of the anchors when I pulled up to set them. I would never trust these things to hold down my canopy. The company was willing to send me replacements but I will no longer trust shelter logic anchors so they refunded my money for both sets”
