Great Call Athletics Professional Football Nylon Chain Clip

The chain never moves on its own. The clip has to be right.

Head linesmen and line judges do not carry gear that fails on a measurement.

High Tensile Nylon Build: Holds shape through heat, cold, rain, and full contact game weeks. The clip survives the season and the next one.
Orange High Visibility Belt: Stays readable from the press box and the sideline. Placement calls get clean sight lines.
Metal Swivel Clip: Locks to the chain without walking. One setup per drive, no adjustments between plays.
Smooth Sliding Marker: Plastic yardage marker moves exactly where you place it. Precision measurements every time the offense lines up.
Officials Tested: Worked by head linesmen at youth, high school, college, and pro levels. The details hold at every speed.

Run the chain. Call it clean.
