K2 Hot and Cold Fill Keystones

We have the standard No.2 and the larger, less common No. 1 sizes available in our range of plastic keystones. Thermoplastic materials are used for keystones that are applied to a hot cask which is then filled quickly thereafter. A lower cost LDPE variant is available, strictly for those who fill cold casks.
