The Panther Wall Spreader (138966) is a telescopic spanning system which is able to withstand heavy loads.
It’s a perfect tool on sets where lighting stands are not allowed or not possible. It can be set up very fast, easy and without damaging the walls.
By spanning the Wall Spreader between two solid walls, the telescopic poles form an arch. This arch points upwards (similar to a bridge), allowing it to take considerable loads, e.g. lighting fixtures.
 
So, if your space on set is limited (for example stairwell), you can bring your lighting equipment exactly to the position you prefer.
