The Big League nail drag is designed to provide the most uniform scarification available. The secret is in the design! This nail drag features three crossbars, each containing 2 rows of smaller diameter, finely pointed spikes. Each row is individually off-set and staggered providing a narrow 2/3" of spacing. This design provides the smoothest and most manicured scarification available and allows you to more uniformly blend conditioners into your infield clay. This is simply the best drag for breaking up hard, compacted surfaces and helps to dry out moist infield clays. The spikes on this nail drag are 6" long and you can add weight to increase the depth. The super heavy-duty box structural steel construction has a powder-coated finish.
