This is the AIR TRACK OPERATION BOOSTER KIT.

It contains a set of parts for expanding the standard MF0133-001 operation kit. The booster kit is the same for both 2m Air Track and 2.5m Air Tracks.

The booster kit is an additional kit of parts to extend the standard kit. It includes a heavy ‘Stop Block’ mounted on a felt lined piece of glider material that can be positioned part way along a track to divide the track into separate sections so that two students can perform experiments simultaneously. The heavy block is fixed to the felt lined glider with a special screw and nut.

Genuine IEC product.
