MODEL 7970 MULTI-SIZED SPRING SECURITY OVERHEAD CONCEALED CLOSER
The Norton Rixson 7900 Series Overhead Concealed Door Closer is perfect for high-end architectural openings that require both durability and a sleek look. It's built tough to withstand vandalism and tampering, making it ideal for high-security locations. And for detention and psychiatric facilities, the 7970 Series security closer offers added concealment and tamper resistance. With the door position switch (DPS), you can even monitor the door status remotely. These concealed door closers have adjustable spring sizes and can hold the door open at multiple points. They also have a shock-absorbing door stop, adjustable sweep and latch speeds, and cushioning for backchecking. They work with different types of hinges and can accommodate a range of door thicknesses. For security doors, there's even a special model (7970(DPS)). Plus, you can add optional door closer features like delayed action or enhanced backcheck.
