Product Description
RX78DT-US15-4 Von Duprin 78 Series Request to Exit Dummy Pull Rim Exit Device in Satin Nickel
The Von Duprin RX78DT-US15-4 is a crossbar rim exit device for storefront and aluminum doors. Dummy Trim — non-functional outside pull for appearance. Provides a handle on the outside without any latch control. No cylinder required for this function.
The 78 Series crossbar provides a wide activation zone across the full width of the door — maximum push area for emergency egress. Available in 4-foot width. Non-handed design works for both LHR and RHR door swings. UL listed for panic exit hardware with hex key dogging standard. ANSI/BHMA A156.3 Grade 1 certified.
Pro-Tip from Our Locksmiths: The 78 Series rim device gives you a crossbar exit on wide stile storefront doors. Available in both 3-foot and 4-foot widths. If you're coming from a 22 Series pushpad, note the 78 crossbar has a wider activation zone — better for ADA compliance on high-traffic entries.
