Von Duprin QEL3550AWDCEO | Grade 1 Concealed Vertical Cable Exit Device With Quiet Electric Latch Retraction For Single and Double Wood Doors, Smooth Mechanism Case

The Von Duprin QEL3550WDCEO is a grade 1, concealed vertical cable exit device for single and double doors. The device features quiet electric latch retraction, which allows remote latch retraction. Quiet electric latch retraction is a feature that can be used in places where low operational noise is required such as hospitals, museums, libraries and theaters. Latch retraction of this Von Duprin QEL3550WDC wood door concealed vertical cable exit device can be either momentary or for extended time periods.

The Von Duprin QEL3550 wood door concealed vertical cable device is a great alternative to use in place of a traditional concealed rod device, when installation conditions are less than ideal. For example, if the top latch, device centerline and bottom latch are not vertically aligned, then the flexibility and slack in the cable system allows the device to function properly. Further, the Von Duprin QEL3550WDC wood door cvc featuring qel, requires less maintenance than a traditional rod device.
