ABSTRACT:
Covers for U-channel or C-channel sign posts comprise an extruded hollow plastic form having a length, the form in cross-section including a generally flat front wall and opposing generally flat side walls. Each side wall converges toward the other at an angle from the front wall to a back section having a width less than the front wall, thereby forming a generally trapezoidal interior. Each side wall is bent toward the other to form overlapping portions that make up the back section. In the preferred embodiments, the front wall further includes a co-extruded reflective, fluorescent, phosphorescent or colored lengthwise strip of material to enhance visibility, and the back section further includes an engagement mechanism between the overlapping portions including one or more sets of engaging barbs. The back section may further include a rearward wall extending from one of the overlapping portions and folded over the overlapping portions forming a rearward wall to assist in maintaining the engagement of the barbs.
