    3) How do I determine the correct handing for this device?
    Stand on the egress side of the door. If hinges are on your right, order right-hand. If hinges are on your left, order left-hand. The 33A-F series requires specific handing during ordering as field conversion is limited.
    4) What finishes are available for the 33A-F series?

    8) What are the basic installation requirements?
    Installation requires mounting the device to the door face and strike to the frame. Use manufacturer templates for precise positioning. Ensure proper door alignment and clearances. Professional installation recommended for fire-rated applications.
    9) How do I maintain and adjust the 33A-F exit device?
    Regular maintenance includes cleaning mechanisms and checking for smooth operation. Lubricate pivot points annually with manufacturer-approved lubricants. Adjust latch projection and strike alignment as needed. Avoid field modifications that could affect fire rating.
    10) Are there related models or substitutes for the 33A-F?
    The Von Duprin 99 series offers similar functionality for standard stile doors. The 35A series provides surface vertical rod options. For narrow stile applications, the 33A-F remains the preferred choice. Browse exit devices for alternatives.
    11) What field conditions affect installation performance?
    Door warping, frame misalignment, and improper clearances can affect operation. Ensure doors are properly hung and frames are square. Temperature changes may require periodic adjustments. Address wind load considerations for exterior applications.
    12) What are the key measurements needed for ordering?
    Measure door thickness, stile width, and frame depth. Note the distance from door edge to obstruction. Verify backset requirements for trim compatibility. Standard narrow stile dimensions are typically 2 inches but confirm exact measurements.
