Von Duprin 88EO US26D-4 – Frequently Asked Questions

1) What door widths work with the Von Duprin 88 series 4 ft wide stile crossbar rim exit device?
The 88 series handles doors up to 48 inches wide with the 4 ft crossbar configuration. Standard applications cover 32-48 inch door widths. Verify your door width against the device length for proper coverage.
2) How do I determine the correct handing for this exit device?
Stand on the egress side facing the door. Right hand if hinges are on the right, left hand if hinges are on the left. The 88 series crossbar can be field-reversed for opposite handing if needed.
3) What is the difference between rim, mortise, and vertical rod configurations?
Rim devices mount on the door surface with a rim cylinder. Mortise versions fit into door pockets. Vertical rod adds top and bottom locking points. This rim model provides single-point locking at the strike.
4) Can I add electric latch retraction to the Von Duprin 88 series?
Yes, the 88 series accepts electric latch retraction options. Common choices include 12VDC and 24VDC solenoids. Electric trim and power supplies are ordered separately based on your access control requirements.
5) What finishes are available for the 88 series exit devices?
Standard finishes include aluminum, dark bronze, and brass. Special order finishes may be available. The device body, crossbar, and trim should match for consistent appearance across the opening.
6) Does this device meet fire door requirements?
Von Duprin 88 series devices are UL listed for fire door applications when properly installed. Verify the specific fire rating requirements for your opening and ensure all components match the door assembly rating.
7) What outside trim options work with the 88 series rim device?
Common trim includes lever handles, knobs, and pull handles with rim cylinders. Electric trim with card readers or keypads is also available. Match trim series and finish to the device for proper function.
8) How do I install the crossbar on the Von Duprin 88 series?
Follow the manufacturer template for crossbar mounting height and spacing. Standard height is 34-44 inches from floor. Secure mounting brackets to the door first, then attach the crossbar mechanism. Test operation before final adjustment.
9) How do I adjust the latch on the 88 series exit device?
The latch projection is adjustable through the device case. Turn adjustment screws clockwise to increase projection, counterclockwise to reduce. Maintain 1/2 to 5/8 inch projection into the strike for proper security.
10) Are there other Von Duprin exit device series I should consider?
The 99 series offers heavy-duty construction for high-traffic areas. The 98 series provides mid-grade performance. The 22 series covers light-duty applications. Choose based on door weight, traffic level, and budget requirements.
11) What door weight limits apply to the Von Duprin 88 series?
The 88 series handles standard commercial door weights up to 200 pounds. For heavier doors or high-traffic applications, consider upgrading to the 99 series heavy-duty models. Check door weight before specification.
