Products > End Closures
Each style of paper tube is used differently and requires an end closure specific to that application. We offer a full line of end closures to compliment our products.

End closures are sold by the case unless they're ordered with paper tubes. Some end closures are stock items; others need to be special ordered. Click here for a custom quote.
