Safety Technology Int'l Inc SS2221NT-EN Stopper Station

Product Description

The SAFETY TECHNOLOGY INT'L INC SS2221NT-EN is a yellow stopper station assembly that includes a tether and stopper shield, designed for use with exit device applications. The bright yellow color provides high visibility, making it easier to identify emergency egress hardware at a glance. This type of stopper station is typically installed by commercial electricians, facility maintenance technicians, or security system installers working in environments where door control and emergency exit compliance are critical priorities.

The SS2221NT-EN is suited for commercial and institutional settings where exit devices require an added layer of tamper resistance or controlled access management. The stopper shield protects the exit device actuator from unintended or unauthorized activation, while the tether provides a physical restraint mechanism. Typical installation scenarios include schools, healthcare facilities, retail environments, and other commercial buildings where door egress hardware must meet code requirements.
