I bought four refurbished pin locks from Cornykeg.com but have decided not to use them. They have red tops. I cleaned one with a magic eraser and it looks almost new.
I got rid of the original lids and purchased universal lids with pull tab pressure release valves. Three are still in the original packaging from cornykeg.com. The other I put in the keg to make sure it fit.
I am asking $30 per keg without the new lid or $40 with the new lid.
If you buy all four I will ship for $20 otherwise you pay actual parcel post rates.
