Abstract
A retainer for a drop-in anchor includes a durable, moisture resistant member insertable into a sleeve of a drop-in anchor and configured to be retained in the sleeve by one or more threads disposed in the sleeve to prevent inadvertent removal of a plug from the sleeve. A drop-in anchor assembly includes a tubular sleeve having a first end including one or more internal threads, and an expandable second end. A plug is insertable in the sleeve such that when the plug is driven into an installed position in the sleeve the second end expands. A retainer formed of a durable moisture-resistant material is insertable in the sleeve behind the plug, and is configured to be retained in the sleeve by the one or more threads and prevent inadvertent removal of the plug from the sleeve.
