Frequently Asked Questions

Q. "What's the difference between standard and fire rated outlet boxes?"
A. Standard outlet boxes are simply a box installed between the wall studs to keep valves out of the way yet accessible. These are not rated for use in areas that require fire retardant materials. Fire retardant gas outlet boxes are designed to be used in conjunction with fire retardant building materials to maintain the performance of the fire retardant construction. The outlet boxes on this page are not only constructed of a fire-retardant resin, but they also feature intumescent pads, which is a kind of fire stop putty designed to retard heat transfer in the event a fire reaches the pad.


Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.
