Hand-tighten the Extang SpeedKlamps™

and no tools are needed.
Cab section SpeedKlamps™

tightening, by hand, the
threaded clamp with
built-in heavy-duty handle.
Tail section SpeedKlamps™

technology for
instant fasten and release.
The clamps conveniently

when not in use.
The new Extang
MaxHinges™
are double pivot
hinges with
center link and
padded seals.
These Extang
engineered glass
filled nylon hinges are built to last. One of
the smallest, but most important parts of the
Trifecta tonneau system.
The Trifecta
tonneau cover
has 45 steel
corner brackets
that provide
unparalleled strength.
Extang’s commercial
grade rails and I-beam Monster Bows&trade are
secured with multiple reinforcements using
zinc dichromate, aluminum braces. Together
they offer the strongest, professional quality
tonneau that Extang Engineering is noted for.
Extang uses pro-grade labyrinth rail seals
that exceed OEM standards and provide the
best seal possible. Seals at all contact points
to protect the truck’s finish and keep out
the weather and dust. The permi-sealed tarp
is pre-attached to rails for a permanent seal
and no-gap fit.
The heavy
duty luggage-style Hold-Tite™ fasteners
are quick and easy to use and adjust. The
Hold-Tite™ straps
and snaps combination
allow the tonneau
to be fully open and
safely secured at the
cab while driving.
