Close attention should be placed on crossbar ends as they can have an impact on safety and aesthetics. UL 305 4.3 states:
The ends of the crossbar or push pad shall be curved, guarded, or otherwise designed to prevent catching of the clothing of persons during exit.
Curved crossbar ends are a key feature to look for in tubular panic devices for glass doors. The benefits are twofold. First, they produce a smooth, continuous flow of hardware through the glass, creating streamlined visuals. Second, they improve safety by preventing clothing and carrying bags from getting caught on crossbar ends in case of emergency egress.
Working with an established architectural hardware manufacturer can significantly reduce the risk of specification errors. The manufacturer can help overcome the unique challenges tubular panics and glass doors present by providing design and engineering services, as well as UL-tested products.
While thousands of possible configurations exist, an experienced manufacturer will be able to provide a panic device for nearly every type of door and application, including monolithic heavy glass doors, laminated tempered glass doors, insulating glass, aluminum rail and stile doors, hollow metal doors, wood doors, and balanced doors. Manufacturers should also be able to supply compatible manual strikes, electric strikes, or electric strikes with bolt position sensors.

Conclusion
The appeal of glass entrances is evident. They offer contemporary aesthetics, daylight diffusion, transparency, and unobstructed views. A well-designed and thoughtfully specified glass entrance system can serve as a captivating introduction to a building’s visual theme, while providing the safety features required in emergency exit situations.
As the popularity of tubular panic devices continues to grow, architects and specifiers must recognize the unique design challenges they present. When it comes to life safety, diligence is imperative.
Understanding IBC, NFPA 101, and UL requirements for panic devices, and identifying critical glass entrance design considerations is vital. Working with a certified glass temperer and/or reputable full-service manufacturer will ensure the emergency egress system effectively combines safety, aesthetics, and function for the life of the building.

Bad design. Look up the definition of a Norman Door. Any door that requires a label to tell the user how to operate it is a failed design. The horizontal bar directs the user to push, but the vertical bar suggest that pulling is the answer; conflicting messages for the user.
