FAQ
What is the UNDUX42002?
The UNDUX42002 is an UnderCover Ultra Flex hard folding tonneau cover built for the 5 foot bed on the 2005 through 2015 Toyota Tacoma, offering a matte black aluminum finish and up to 400 lbs of weight capacity.
Does the UNDUX42002 require drilling to install?
No. The Tip and Click mounting system uses the factory bed rails and typically installs in under 30 minutes without drilling.
How much weight can the Ultra Flex cover hold?
It supports up to 400 lbs of evenly distributed weight across the closed panels.
Is the UNDUX42002 weatherproof?
It is weather resistant, using upgraded seals and tight fit clamps to keep out water, dust, and debris under normal conditions, though it is not intended to be fully submersible.
Can I still access my full bed with the cover installed?
Yes. The panels fold toward the cab and lock in the open position, giving 100 percent bed access when needed.
What warranty comes with this bed cover?
UnderCover backs the Ultra Flex with a 5 year limited warranty against defects in materials and workmanship.
Does the cover lock automatically when closed?
Yes. The patented rail and clamp system engages automatic slam latches that lock down every panel as it closes.
Will this cover work with bedside storage boxes?
Check current fitment listings for storage box compatibility, since some Tacoma bed configurations with bedside boxes require a different Ultra Flex part number.
