This is very common on movie sets because it has so many uses. This size speed rail can also be used as track with some dollies such as the Dana Dolly. Normally it is used a lot also for fixed camera rigging on cars and to rig suspension arms like the CineMilled Action Arm and others.
The smaller sizes like the 6″ or 1′ can be used as a “starter” when used on our CineMilled Modular Speedrail starter.
1-1/4″ is the size most commonly used in the USA and 1-1/2″ is more commonly used in Europe.
