LOUISVILLE, Ky. (WDRB) -- Submarine sandwiches are helping to save lives. 

Customers of Firehouse Subs helped fund a grant for the Kentucky 86 Fire and Rescue department in Elizabethtown. It paid for more than $24,000 worth of equipment to outfit junior firefighters for training.

Each restaurant allows customers to "round up" their bill to the nearest dollar, and donate spare change to the Firehouse Subs' foundation.

Firefighters and franchisees thanked the community for their support on Wednesday.

"The foundation is so wonderful in that almost 90 cents of every dollar we help raise actually goes to you guys -- not administrative fees, doesn't go to corporate bills -- it goes to what it needs to go to, and that's a big deal for us," said Sarah Little, a franchisee. 

Since the foundation was started in 2005, its raised more than $31 million in equipment and educational opportunities for first responders across the country.
