Sturdy tent anchors ready for installation

Here are 19 (of 20) steel tent anchors off to their new home. These will be installed using 3-inch lag screws. The loops on the anchors are perfect spots to tie off a huge event tent that is erected on the top of a building. Lots of wind, so these need to be strong. The plates are 1/4 inch steel. They are painted with black enamel paint.
