Thanks for contacting us with your question Herbie.
Yes, locks are available for this Beverage Air GF48L-S 48" Stainless Steel Glass & Plate Chiller. That said, the locks are installed at the factory when the unit is ordered. If you already have this unit, you'll need Beverage Air part #00C30-101A (the lock) and will have to install the locks yourself.
If you'd like to order this unit with locks, or if you'd like to place an order for the locks themselves, please give a member of our Tundra Restaurant Supply team a call at 1-888-388-6372. Be sure to specify you want door locks if you're calling to order the entire unit.
