How they work
Crash Blocks are a carefully designed innovation that works with existing
header extrusions. Precisely fitted, the devices slide smoothly within
the header. The jamb-side wheel bracket from each door is set into the
device's opening. One Crash Block stays with each door, sliding freely
with the wheel brackets. The light friction from the devices add a comfortable
'hydraulic' feel to the doors' movement.

The Crash Blocks design also incorporates a shock-absorbing flexible
arm for abusive or overly forceful situations, and an anti-jump
feature where the wheel brackets are blocked from jumping the track.
These devices are doing several jobs while remaining discreetly
concealed within the header. Most users won't even know that they're there.
