• Fine Tip Sharpie or other fine tip marker
• Centerpunch
• Power drill with sharp drill bits/Step Bit
• Airsaw (our preference) or jigsaw with fine tooth metal cutting blades
• Philips screw driver for the compression latch.
• 8mm wrench/socket for tightening the hinge nuts.
• 11/32" wrench/socket if your kit was shipped before August 2025 and a 7mm wrench/socket if your kit was shipped after this as we've switch to all metric nuts to attach the locker to the vehicle.
• Painters Tape
• Masking paper can be helpful
• Isopropyl Alcohol to clean inside cavities
• Paper towels or shop rags for cleaning the wax from the inside cavity
• Black Spray paint if you want to paint the inside

Rather than using the inner pieces as the template we've now included 2 think cardboard templates. Why 2? Well just in case one gets damaged on the first side.

!IMPORTANT: Once the locations are marked it's very important that you follow proper drilling best practices to ensure holes are centered and in the correct place. There is not a lot of margin for error here, so if you don't feel comfortable or confident or have the right tools, professional installation is highly recommended. Moonraker Design Co. will not be held responsible for incorrect installation.

• Centerpunch each hole location
• Center drill or pilot drill with a nice sharp small split tip cobalt drill or purpose made center drill.
• Drill to size using the recommended drill sizes below.
• Debur the front & most importantly back side of the hole.
• Apply anti-corrosion treatment after test fitting. Our preferred is Rust Bullet.

The correct offset is already incorporated if you cut along the inside of the tempaltes. We added support ribs on the template to stiffen it up. So after you mark you will need to connect the lines to get a full perimeter cut line.

Once the line has been drawing you'll want to drill close to each of the four corners to give you space to insert your Airsaw or Jigsaw blade. It can also help if you apply painters tape around the outside of the cutline to protect the paint. It will be covered with the trim ring, but it's still good practice to keep the paint intact whenever possible. If you do scruff or scratch the paint be sure to apply a rust preventative paint over those areas prior to installing the trim ring.

Once you've cut the hole and drilled the mounting holes be sure to check fitment. You may need to open up some of the stud holes slightly to get the trim ring to seat fully. Once it's seated fully, make sure there are no visible edges from the center hole. If there are grind/sand or cut those back until they no longer show. Use a grinder, sander or file to smooth all sharp edges and treat with rust preventative paint.

AGAIN... Make sure you add proper rust preventative measures to all drilled holes and cut metal. Our preferred product for this is Rust Bullet, it's by far the most durable and best paint we've tested with the only draw back being the 2 hour dry time. We put together at YT Short showing all the supplies we use.

The first nut you should put on is the top most front. It's pretty difficult to get started. You can check the video here for how best to do it. (Update as pf 04/26/2025 this is a lot easier as the design has been updated after this date to move the location of this screw). All the others are pretty easy. Tighten them all a bit at a time to get a uniform compression of all the pieces together.

Tighten until everything is snug. Be sure not to over tighten our target spec for these nuts is around 1.5 – 2.0 Nm (13 – 18 in-lb)

It's important to use the included anti-sieze on each of the hinge studs prior to installing the nuts. This will prevent galling from the same material types. You don't need to add a lot, just a little dab to the end of each before you install them.

Anti-seize is notorious for getting everywhere, especially if you get it on your fingers so I like it use a small foam applicator or q-tip to put it only where I want it.

I like to install the hinges to the van/trim ring first then attach the door. You'll use the same 8mm wrench to do so and remember to add anti-seize the same as before.

Once the door is attached you can add the compression latch, it's shown how to install it pretty well in our original video here. You may need to adjust the compression latch to get the right compression to seal the door, but don't over compress. The door should be tight and flush all around. Also don't forget to add the seal when putting on the compression latch.

Another good example from the video here on how I do this. I send along plenty of extra so it's best to unroll it and cut it in half, one piece for each side. if you contaminated the surface with any anti-seize or loctite be sure to clean it prior to adding the gasket.

Choose a starting point on one of the vertical edges and work your way around the perimeter. Cut to length at the seam and stick it down.
