EA-75, -76, -77, -78 Precision Air Tracks
The Precision Air Tracks are the finest air track available. The track and its heavy support beam make a strong stiff structure that can be built in long lengths if needed. We have built these tracks up to 7.5 m long, but they are usually no longer than 5 m. Straightness throughout its length can be adjusted by the many studs connecting the track and the support beam. These tracks are available in lengths from 1.5 to 5 m and are recommended for the most critical applications. They come with a wide selection of accessories to carry out most friction-free dynamics experiments.
