Product Description
3327A-T-F-US28-4 Von Duprin 3327A Series with 360T Thumbturn Fire-Rated Surface Vertical Rod Exit Device in Anodized Aluminum
The Von Duprin 3327A-T-F-US28-4 is a touch bar surface vertical rod exit device from the 33A Series family. Thumbturn — inside thumbturn controls the latch. Common on 33A/35A series. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
The 3327A uses surface-mounted vertical rods for top-and-bottom latching. Standard choice for pairs of doors where both leaves need to be active. Available in 4-foot width. UL listed for fire exit hardware — no mechanical dogging on fire-rated models. ANSI/BHMA A156.3 Grade 1 certified.
Pro-Tip from Our Locksmiths: Surface vertical rod devices need proper strike alignment at both the header and threshold. If either strike pocket is too shallow — common on older frames — you'll need surface-applied strikes. Check before you order.
