Product Description
9948TP-US28-4 Von Duprin 9948 Series with 990TP Thumbpiece Trim Concealed Vertical Rod Exit Device in Anodized Aluminum
The 9948TP-US28-4 is a Von Duprin 99 Series Rim exit device in Aluminum (US28/628), sized for 4' doors. Thumbpiece Trim — thumbpiece-operated outside trim for keyed entry. Night latch function with thumbpiece activation. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: Rim devices are visible on the door interior, so they're typically used on utilitarian doors (back exits, service doors, storage rooms) rather than customer-facing entrances. But they're reliable, affordable, and quick to install — spec them when aesthetics aren't the priority.
