12.1.2. Spike Impact Direction
The CLAWS Spikes are designed to take a much larger impact in one direction. Thus, the
CLAWS Spikes can be installed to take larger or more frequent impact in one direction.
In other words the spikes can be installed to face either towards oncoming tra ffi c
(similar) or face towards tra ffi c (opposing) trying to enter from the wrong direction
or lane.
There are four types of typical installations. Refer to Section 12, Figures 2 and 3 to
determine if the installation is left- or right-hand orientated.
Secondly; pay attention to the spike impact direction:
• Similar direction of travel prevents vehicles from exiting whilst the boom pole is
still down (Normal direction of tra ffi c)
• Opposing direction of travel prevents vehicles entering against the fl ow of tra ffi c
whilst the boom pole is down
