Abstract
A protective device for a culvert pipe has a generally conical screen portion extending between a base member at one end and an apex member at the other end. The base member is annular about an opening sized to receive the open end of the culvert pipe therein. The apex member may take the form of a domed cap, or an annular ring structure. The screen portion is formed of a plurality of rigid members between opposing first and second ends which are arranged to be selectively mounted to the base member and the apex member respectively using threaded fasteners. The two apex members may thus be interchangeable with one another.

A protective device for use with a culvert pipe having an open end, the device comprising:
- a screen portion which is generally conical about a longitudinal axis that extends between opposing first and second ends of the screen portion;
- a base member supported at the first end of the screen portion in which the base member is generally annular in shape about a base opening therein and in which the base opening is sized to receive the open end of the culvert pipe therein;
- and
- an apex member supported at the second end of the screen portion;
- the screen portion comprising a plurality of rigid members spanning generally longitudinally between respective first and second ends which are arranged to be selectively mounted to the base member and the apex member respectively so as to be readily releasable therefrom.
