ACKPads can be moulded to the shape of the truck, fit around its base, and connect directly to an existing tiller arm anti-crush stomach button. WHC says this increases the detection area of an impact typically by more than 800%.

The ACKBelt has been developed to give quick and easy fitting to almost any shape, following its form. ACKBelt's can be retrofitted to most makes and models of trucks, so are suitable for mixed truck fleets.
