Pole to Flat Hoop clips.
These extremely useful little clips rotate. Which allows you to attach a hoop horizontally, as a basketball-type target, or to a pole vertically as a target 'window' to aim at and hit or throw through. And vary the height.
Which means you can create coaching equipment according to the age and stage of your players.
They will also hold card or laminated paper - for numbers, for example, if you've created a series of activity stations, or instructions.
