For many years I have used screw type anchors for securing my glider trailer.  They are very time consuming to install and remove and physically draining.  I am now using The Claw.  It installs in a very short time and is also extremely easy to remove. 

Note: Not recommended for long term use because any temporary anchor will loosen over time.  Designed for use with the load pulling straight up.  The capacity is reduced dramatically when the load is applied from the side.  Also, this system will work differently in different types of soil. Obviously, heavy clay or soil with turf on top is better than sandy or rocky soil.

Note: This item is somewhat expensive to ship due to the high weight.
