hinge lock tabs interlock.

PRE-INSTALLATION NOTES:

1. Install the Bulkhead Prep Kit before installing
your DiamondBack cover. Refer to the Bulkhead
Prep Kit Installation Guide for details.
2. If you are installing a Low-Profile Cab Guard
or HD Cab Guard, you should mount it prior to
installing your DiamondBack. Refer to the Cab
Guard Installation Guide for details.
3. If you are installing a Side-Loading ATV Carrier
on cargo bed longer than 6 feet, you must mount
the center panel adapter bars prior to installing
your DiamondBack HD. Refer to the Side Adapter
Bars Installation Guide for details.
4. It's possible for one person to install a DiamondBack
solo, but the whole process, especially positioning
the panels and adjusting the lock rods, is much
easier with two people.
Mating hinges is
easiest when you
line up the longer,
left hinge pin first.
