This is the bulk purchase option for Dunlop Fort All Court High Altitude – the altitude-corrected version of the Wimbledon-grade Fort ball, sold in a case of 24 cans (72 balls total) at a significantly reduced per-can cost.
For clubs, academies, and coaching operations based on the Highveld – Johannesburg, Pretoria, and surrounding areas – bulk stocking of high altitude balls is the operationally sensible approach. Using sea level balls at altitude produces an inconsistent, faster-bouncing, harder-to-control ball that doesn’t reflect proper tennis conditions. High altitude specification is the correct equipment choice for all regular play above approximately 1,200 metres.
The Fort All Court High Altitude delivers the same premium construction as the sea level version – durable felt, consistent bounce, ITF-approved specification – in the pressure-adjusted format designed for Highveld conditions. Clubs can maintain consistent training and match conditions using the correct ball specification throughout the season.
Cases are stored unopened to preserve pressure until needed. Case contains 24 cans of 3 balls.
