RMC Supply Co. is a small manufacturing company located in Arnold, MD. It is our goal to provide high quality products, including our Elevator Sump and Oil Alarm Systems that are easily and quickly installed, meeting all existing codes.

Our systems ensure that no oil from the elevator sump pit will be pumped into a municipal waste water system.

We ship direct to the end user, throughout the US and Canada. This allows us to keep costs very low relative to any other product on the market.

Our installation, operation and safety record has a 100% customer approval rating.

We strive to provide the best systems at a reasonable cost, with ease of installation and a minimum lead time. Most components are stocked or available to ship within a few days.

We have the ability to customize any system to unique specifications.

We welcome any inquires you may have concerning our products and reputation in the industry. Please feel free to contact us today.
