FENCE
30 years.
On stage.
At the Klagenfurt City Theater.
A system. And still on stage.
Our FENCE fly system from the Klagenfurt City Theater is returning to us after 29 years—during the “theater break,” the off-season. Time for a thorough maintenance check.

Inspection of the entire system, replacement of rollers and ball bearings, modernization of motors and the control system, followed by reassembly and thorough test runs.
After all, our products have stood for sustainability and durability for 80 years. Thanks to high-quality manufacturing, they are particularly robust and built to last. Furthermore, our products can be technically overhauled and modernized, which significantly extends their service life and conserves resources.




Then it’s back to Austria, accompanied by two of our technicians—and the curtain will be fully operational again in time for the start of the new season.
FENCE—the professional main curtain system
Designed for heavy theater and opera curtains, FENCE stands for precise movement, maximum operational reliability, and exceptionally smooth operation.
Since 1997, GERRIETS has delivered more than 146 FENCE scissor hoists worldwide, with a total of over 3,000 meters of track.
29 years later: back in the workshop.
Not because FENCE has to—but because we want to know what it’s really capable of.
FENCE. Built to perform. Built to last.
