We are pleased to announce that we have developed a new and improved 28-400 closure which will be replacing our current 28-400 closure. The new 28-400 features an improved gate vestige, "L" style threads and friction fit liners (click here for more details on the new 28-400). Our plan is to discontinue selling the old 28-400 closure on October 31, 2018. We'd love to send you samples of the new closure! You can click here to fill out a sample request or just give us a call at 1(800)356-8483. Our goal is to keep this conversion as seamless as possible. Don't hesitate to contact our Customer Service Department if you have any questions.
