Gill Replacement 4" World Athletics Foul Board

The 4" World Athletics Foul Board is the dedicated replacement component for facilities running Gill's 4351S World Athletics-certified take-off board setup. Positioned alongside the 8" take-off board to complete the full 12" system, the foul board plays a critical role in foul detection under World Athletics technical rules — making its condition directly relevant to competition integrity.

• World Athletics Specific Configuration – Sized and designed to meet World Athletics (IAAF) technical requirements for long jump and triple jump foul detection, making it the correct replacement for facilities certified under international competition standards
• 4" Width Foul Board – Pairs with the 8" composite take-off board to complete the regulation 12" combined system width required for World Athletics sanctioned events, restoring the full competition-legal setup when the original board reaches end of life
• Polyboard Composite Construction – Built from the same environmentally friendly, waterproof Polyboard composite material used across Gill's take-off board lineup — resistant to warping, splitting, and cracking under outdoor conditions and repeated athletic contact
• Direct System Compatibility – Fits the Gill Adjustable 12" Take-Off Board System (4351S) installation without modification, dropping into the existing tray and base hardware for a straightforward swap
• Extends Full System Life – Replacing the foul board alone rather than the entire system significantly reduces maintenance costs for facilities that host World Athletics-level competition on a regular seasonal basis
