Von Duprin 3547AEO-F 3 US28 – Frequently Asked Questions

2) Is this exit device compatible with aluminum storefront doors?
Yes, the narrow stile design works with aluminum storefront and curtain wall systems. The concealed vertical rod mechanism provides clean aesthetics for glass door applications.
3) How do I determine proper door handing for installation?
Stand on the secure side facing the door. If hinges are on your right, order RHR (right hand reverse). If hinges are on your left, order LHR (left hand reverse). Verify handing before installation.
4) What finishes are available for the 3547A-F?
Standard finishes include aluminum, dark bronze, and black. The smooth case provides consistent appearance. Check with manufacturer for custom finish options on large projects.

No, this model is specified as "less dogging." The device cannot be held in the retracted position. This ensures positive latching for fire-rated applications.
7) What accessories are needed for complete installation?
You'll need strike hardware, mounting screws, and gaskets. Top and bottom rod assemblies are included. Check manufacturer specifications for required glass stops and reinforcement plates.
8) How is the vertical rod mechanism concealed?
The rod assembly runs inside the door frame structure. This provides clean sight lines through glass doors. Proper door preparation is critical for concealed rod installation.
9) Can this device be field adjusted after installation?
Yes, latch projection and rod tension can be adjusted in the field. Use manufacturer's adjustment procedures. Avoid over-tightening to prevent binding or premature wear.
10) What other Von Duprin models are similar to the 3547A-F?
Consider the 3546A series for non-fire rated applications or 3548A for different door configurations. Browse our Von Duprin collection for comparable models.
