"We have not heard from them and have not made an effort to contact our clients in the area out of respect," said Perry Sheldon, Presray's director of field operations.

The installation is part of a renovation project at the Academy in response to damage from Hurricane Isabelle in 2003, Sheldon said.

One is a hinged door; the other, a sliding door.They weigh between 2,000 and 3,000 pounds and are designed to hold back 20 feet or 35 tons of water.

More companies are investing in such protection across the country, said Presray field operations director Perry Sheldon.

"They save the store and all of its contents," Sheldon said.
