“Where safety dictates a crush-resistant door, there’s no substitute for the Zero Man Door,” says mining veteran Larry Cassidy, who has installed hundreds of Zero Man Doors in Consol Energy, Inc., operations.

The RL-12 features the same sure-tight latching handles and secure fiberglass gaskets that earned the Zero model its reputation for raising efficiency and decreasing power costs in ventilation systems. “But the RL-12 is value engineered for all those places where load-bearing capacity isn’t critical,” says Vice President, Tom Flickinger.
“Miners tell us that, in about four out of five cases, all they need is a lightweight door that goes in easily, operates trouble-free, and maintains a tight seal.” The RL-12’s simple unibody construction simplifies handling and installation while retaining key safety features like rolled, no-snag door edges; high-visibility warning reflectors; and an exclusive auto-close mechanism that eliminates slamming and keeps hands and feet out of harm’s way. For safe passage between high- and low-pressure spaces, the RL-12 comes with a built-in equalizer port that doubles as a rock-dusting access point.
“Where safety dictates a crush-resistant door, there’s no substitute for the Zero Man Door,” says mining veteran Larry Cassidy, who has installed hundreds of Zero Man Doors in Consol Energy, Inc., operations. “But the RL-12 is about half the weight and about half the price of the Zero. It still has the best air seal in the industry, to keep more air flowing out to the mine face. And two guys can put one up in less than an hour. It has two parts and you use one tool. So, for a lot of applications, I’d go with the little brother.”
According to Mr. Flickinger, input from miners, mining engineers and mining operations managers drove the RL-12’s design, engineering and manufacture. It comes in standard sizes from 30” x 30” to 42” x 60,” all with adjustable frames to fit 6-inch, 8-inch, and thicker stopping walls.
