These Keg Lid feet are fairly universal and fit most keg lids, including Ball Lock and Pin Lock kegs, with the known exception of AEB style lids. These are "flat" style feet in comparison to our other listing which are more rounded. These are also a bit longer, so they may work well if you're having trouble with a lid securing tightly to your keg. Sold individually, not as a pair. Also, see bulk sale details, as you save money the more you buy on these.
