FOR SINGLE OR GROUPED
The chain opener can fitted to most styles of aluminium,
timber , or steel windows using the appropriate fixing brackets. Controlled
from a wall mounted operator connected via lenghts of conduit and inner
cable to the chain opener on the window.
When the handle of the operator is turned the inner cable
is driven forwards or backwards inside the conduit. The moving cable engages
the cog wheel of the opener , driving the chain out to open the window.
Depending of height limitations , vents can be opened
250 mm or 380 mm, with suitable openers.
A very flexible system as the conduit can be bent to go around pillars
and other obstacles, usinfg the special bending tool and fixed to the
wall or framework with saddle brackets.
To allow for the forwards and backwards movements of
the inner cable , a length of spent travel conduit, must be fitted at
either end of the controll path
i.e. past the last chain opener and below the operator. (except the H35060
operator which has an integral spent travel tube)
