Door Knob Trim DDPD016 is a stainless steel trim solution used with panic exit devices to provide controlled exterior access and reliable mechanical performance in high-traffic environments. Classified as Grade 1 and featuring a non-handed structure, this model supports flexible installation across various door orientations without the need for reconfiguration. The cylindrical body incorporates hardened steel components and a heavy-duty tailpiece, ensuring consistent operation under frequent use conditions in commercial settings. This trim accommodates door thicknesses of 1-3/4" and 2-1/4", with a 3-1/2" rose diameter and compatibility with standard 161 cutouts, making it suitable for a wide range of door hardware systems. The patented clutch function helps protect internal components by disengaging under excessive force, improving durability and reducing maintenance frequency. Finish options including 32D, US3, and US4 allow alignment with different project design requirements.
