The Von Duprin 990K Trim is known as a Knob Trim. This plate mounts on the exterior of the door, and the welded on mounting studs line up with the 99 device on the interior of the building. If you have a different manufacture or a different Von Duprin series on the interior, it will not line up. On the back of this plate we usually find the number 990 stamped on it. The key locks and unlocks the knob. The plate shown here is for the Rim and Surface Vertical Rod 99 and 98 devices. If you have a Mortise or Concealed Vertical Rod, call us and we will order that model. The plate measures 3" wide by 14-3/16" tall. Order here for the 990K-R&V.
