ProTrac is mainly aiming professional users from the theater and show industry.
It is an alternative to two-branch girders (ladders) as a substitute for load bars on prospect trains. ProTrac has high load reserves and high lateral stability.

ProTrac consists of a rectangular upper profile of extruded aluminium combined with a lower round aluminium tube or profile. Three types of lower profile can be connected to the upper profile:

  1. Tube with slot profile 48,3 mm
  2. Tube with slot profile 48,3 mm, with integrated rail filing for Helm 100 runner
  3. Tube with slot profile 60 mm,with integrated rail filing for Helm 100 runner

The lower profile connects to the upper profile with stud bolts. Suspension points for the Pro Trac components slide into the slot of the upper profile and are easily fixed, due to a lock and load system. ProTrac is a modular system.
Variable lengths can be connected via inter­nal tubes, which are bolted into place. The connection of two lower profiles is placed under 45 degrees to guarantee flawless runner travel. ProTrac's profiles are black anodised and are furnished with rubber caps at the ends. The upper profile can be fitted with extra drilled holes of 50 mm (spaced 500 mm) to provide fittings for integrated electrical sockets.
