Clover U-Channel 90° & 180° Post Cap

The Clover Bracket replaces the need to stock separate 90° and 180° U-Channel caps. Its distinctive four-leaf clover profile accommodates both orientations with a single bracket — simplifying inventory, improving cash flow, and giving crews the flexibility to adapt in the field. Compatible with all standard U-Channel posts and both flat and extruded sign blades.
