series 20
Series 20 straight sliding systems are suitable for timber or
metal doors with a maximum panel weight up to 70kg (using
two 2 wheel hangers per door), or 90kg (using two 4 wheel
hangers per door). Components suitable for use with straight
sliding systems are detailed below. Generally two hangers
are used on each door panel. A third or fourth hanger can
be used to increase door weight capacity. eg. using three
20-23 hangers would allow a door panel weighing up to
135kg to be used.
When using upper track support brackets they should be
fixed at 600 - 1000mm spacing. Steel track is pre-drilled
for soffit fixing at 600mm centres and may be fixed directly
to the substrate. Aluminium track is not pre-drilled and will
require support brackets.
