I purchased a Kozyard gazebo and was advised to use these sleeve anchors for securing it to concrete. I’m so glad I followed the recommendation! The installation was easy, and the anchors held the gazebo firmly in place. We recently experienced a 60mph hurricane, and I was amazed to see that the gazebo suffered no damage whatsoever. These anchors truly did their job and provided the crucial stability needed during such extreme weather. I highly recommend them for anyone looking for a reliable, heavy-duty anchoring solution!
