response to the many requests from Porsche drivers looking for a harness guide
bar that would not only guide their driving harnesses, but allow them to mount
their harnesses directly to the bar, we developed the "Harness Truss". The
Harness Truss has been tested and certified to handle types of forces required
by the National Highway Traffic Safety Admin. DOT and SAE J385 Rev.MAR 95, Motor
VehicleSeat Belt Anchorages-Performance Requirements. Strong, yet it weighs only
a fraction of what a support of the same strength made from tubular or bar steel
would weigh. The Harness Truss is precision water-jet machined for a perfect fit
into Porsche factory mounting points. This type of machining is accurate and does
not create heat effected areas in the metal which can alter tensile strength.
Strength requirements for harness mounts are considerably greater than those for
harness guide bars since they must support the entire load applied to the belts.
A mount really can't be relied on unless it has been tested to support the loads
required by the National Highway Traffic Safety Administration.
The material of the bar is
6061-T6 aluminum skeleton and reinforcing bar with type 304 stainless steel
Finish is anodized aluminum with satin stainless mounting brackets. The weight
is 9.44 lbs.
Will fit all 1969 - 1998 911 Coupes. This bar attaches to factory mounting points in
the "B" pillars.
