DATOUBOSS 2M Drop Pantograph for Studio Photography Ceiling Rail System Photographic Pantograph Kit with Pulley, Safety Rope Accessories

Funciona perfectamente.

I purchased this originally not sure if it would mount to the ceiling truss in our studio. Not the track system you normally buy this with. It actually has a track trolley with a 5/8 pin This mounted right to the truss clamp with 5/8 pin I have. The up/ down works great with a safety to keep it from falling - you need to be able to reach it to unlock. Currently, a light is mounted very securely to it - it moved up and down - out of the way very easily - works great.

The pantograph was being used with an Einstein and PLM. Both which are very lightweight. Within the first week of using the metal bars were bent and by two week, it is completely distorted. So much so that the pantograph and barely be move up and down. Very poor quality and can no longer be used. Very disappointed since it was too late to return it and get my money back.

This is the best pantograph I've ever owned, and I've owned 5. Well built, handles a lot more weight than I feel comfortable using on my track system. Although I know how to use these things, it would have been nice to have some instructions.

Great addition to the photo studio. I can position a studio light wherever I want. Very useful.
