Thanks for the question Serena.
The Thunder Group ALPC002 Aluminum Wok Cover should fit your 13.75" wide wok, but it won't fit perfectly around the outside edge as it's half an inch smaller than your wok.
A member of our Tundra Restaurant Supply would be more than happy to talk wok covers with you over the phone. Give us a call at 1-888-388-6372 if you have any more questions.
