Von Duprin VON-3348A-3-628 – Frequently Asked Questions

1) What doors are compatible with the Von Duprin 3348A/3548A concealed vertical rod exit device?
This device fits hollow metal and wood doors with standard 1-3/4" thickness. Door width must accommodate the 3-foot rod length. Verify door construction can support the vertical rod mechanism and header strike installation.
2) How do I determine the correct handing for this exit device?
Stand on the egress side (side you exit through). If hinges are on your right, order RHR (right hand reverse). If hinges are on your left, order LHR (left hand reverse). The concealed rod design requires specific handing for proper operation.
3) What finishes are available for the 3348A/3548A series?
Standard finishes include US3 (bright brass), US4 (satin brass), US10B (dark bronze), US26D (satin chrome), and US32D (stainless steel). Verify finish availability for your specific model number when ordering.
4) What grade rating does this Von Duprin exit device carry?
Von Duprin exit devices typically carry Grade 1 ratings for heavy-duty commercial applications. Check the specific model documentation for ANSI/BHMA certification details and cycle testing results.
5) Does this device meet fire door and building code requirements?
These devices are designed for code compliance including UL fire ratings and ADA accessibility requirements. Verify local code requirements and fire door labeling needs with your AHJ before installation.
6) What components are included with the 3348A/3548A exit device?
Standard package includes the exit device body, concealed vertical rod, top and bottom strikes, mounting hardware, and installation template. Electric latch retraction components sold separately if needed.
7) How is the concealed vertical rod mechanism installed?
Installation requires routing the vertical rod through the door core to connect with top and bottom strikes. Use manufacturer templates for precise strike placement. Professional installation recommended for proper alignment and operation.
8) What door preparation is needed for this device?
Door requires mortising for the device body and drilling for the concealed rod passage. Frame needs strikes mortised at head and threshold. Follow Von Duprin templates exactly for proper fit and function.
9) How do I adjust the latch projection and rod operation?
Latch projection adjusts via screws in the device body. Rod tension adjusts through the top strike mechanism. Make small incremental adjustments and test operation after each change. Consult installation instructions for proper adjustment procedures.
10) What related Von Duprin models are available for different applications?
The 33A/35A series offers standard rim and mortise devices. 98/99 series provides heavy-duty options. 22 series covers narrow stile applications. Browse our Von Duprin selection for complete options.
11) What field conditions affect concealed rod exit device performance?
Door and frame alignment critical for smooth operation. Building settling or improper installation can bind the rod mechanism. Regular lubrication of moving parts prevents weather-related sticking in exterior applications.
12) What are the key measurements for the 3-foot vertical rod configuration?
The 3-foot designation refers to the vertical rod length, suitable for standard commercial door heights. Device body typically measures 1-1/4" projection from door face. Verify exact dimensions against door and frame specifications before ordering.
