🛑Fighting hidden fees and filing shipping claims shouldn't be part of your to-do list.

If you're using a collect account for your enclosure shipments, you're likely paying for it in unexpected costs. Carriers bill enclosures based on carton size rather than weight, and those dimensional surcharges add up quickly. We’ve teamed up directly with our carriers to secure aggressive, product-specific rates to help cut your costs.

Additionally, if a package ever has an issue, we file the claim and send a replacement fast. 📦✨

We’re proud to recognize Rich as this year’s Polycase “Living Our Values” award winner.

For nearly two decades, Rich has played an important role at Polycase, not only as a technical resource but as someone who helps keep our culture strong. He wants everyone to find success and happiness and is willing to make personal sacrifices so that others can excel. Rich cares deeply for the people in the building and Polycase.

But Rich’s impact goes far beyond the visible moments. He genuinely cares about the people around him and is always looking for ways to support, encourage, and celebrate his coworkers. As Polycase has grown and changed, Rich has continued to step up wherever he is needed, always with a team-first attitude.

We’re grateful for everything he does for Polycase and our team.

Congratulations, Rich!
