Rhino 4″ x 6″ H Column Driving Cap

The Rhino 4 in. x 6 in. H Column Driving Cap is a dedicated drive cap for the PD-140 post driver system, designed specifically for setting H-column steel sections used in highway and roadside barrier installations. With a 4-1/4 in. x 6-1/4 in. chuck profile, it seats squarely over the H-column flange and transfers full impact force evenly across the post head for straight, damage-free drives on heavy structural steel.

• Engineered specifically for 4 in. x 6 in. H-column guardrail posts.
• 4-1/4 in. x 6-1/4 in. drive profile seats flush over the H-column flange, keeping the post centered and aligned throughout the drive cycle.
• Must be paired with the 4 in. x 6 in. H Column Guardrail Chuck Adapter.
• Transfers full impact force evenly across the post head, preventing flange distortion or deformation on heavy structural steel sections.
• Built for production-grade guardrail installation crews driving high cycles per day in highway, DOT, and municipal right-of-way applications.
