Real Customers, Real Reviews

I just wanted to take a minute to say thank you for the great service and early delivery of our recent order. We received the machined and printed parts today and were extremely happy with the fit and look. Your folks went above and beyond by milling the inside of the rear panel to insure a connector would work properly. This has been the easiest and most pleasant custom job we've done in the dozen or so years we've used Polycase. Thank you for your advice and for putting me at ease with this super time sensitive project.

Just a quick note to let you know that this is the BEST website I have ever experienced. Very intuitive and professional. I love it! In a space that might appear to be a commodity, you guys have done a fantastic job of differentiation! I can tell you guys put a lot of thought into the quote "process" which doesn't happen often. I can't imagine going anywhere else. Great job!

Peter E.

Polycase is a great place to do business and we understand that depends on the people.

Bryan Y.

The "search by size" feature, CAD models and drawings were very helpful for selecting the right sized enclosures - these were distinguishing features that convinced me to buy from Polycase. I used the enclosures on two projects, the case walls were thick and sturdy, and they worked great. Thank you!

Matt V.

I love dealing with Polycase! You guys have an awesome company.

Michael R.

We've been using Polycase enclosures for more than 15 years. All these years they've shown flexibility with our special requests, and have provided quality enclosures with virtually zero defect. We not only like the products but also the outstanding quotation/engineering/approval/shipping processes behind. Thanks to for their high quality at fair prices with top customer service.

Michel S.

Polycase has been a great partner to work with. They are responsive to all requests.

Cindy P.

I spent a lot of time combing the internet for the right size enclosure at a decent price. I mean A LOT of time...I am so happy to have found your website. Your selection is fantastic and the ability to have it machined takes it even further. The fact that you provided instant quoting, excellent drawings, 3D models, etc. allowed me (who's completely inexperienced in proper enclosures and membrane design) to wind up with a membrane that fits perfectly with what you delivered.
