Manual Window Controls.

Manual remote opening systems can enable a number of high level windows to be operated from one single operator.
The chain opens the window via a rotary control handle, which drives a steel helical cable. The cable runs within a nylon lined steel conduit. The conduit can be formed and installed on-site to overcome any difficult building contours.
