The innovative WingGuard® feature is highly space-efficient
and provides a very low profile design.
To close the clamp, the strap is tensioned to a pre-determined
closing force. Subsequently, two wings are cut and bent to
create a permanent interlock, maintaining the precise diameter.
The remaining band is then cut completely flush with the
housing edge and the residual band is removed for recycling.
The WingGuard® Strap Clamp has a very low spring back
effect and a high residual holding force.
The wings and cut strap are fully enclosed within the housing
envelope and therefore the clamp has no exposed hooks
or edges. This results in design and installation with no risk
of damage to surroundings, e.g. sensitive airbag fabric.
