Step: 1

Get the Necessary Tools

Grab a flexible measuring tape, pencil,

and print our measuring chart.


Tip: Having a partner to hold the tape measure and record your measurements on paper for you is not required. But it could make the measurements more accurate and the process much easier.


Step: 2

Start off on the right foot.

With your measuring guide printed off, start on either the driver or passenger side. Measure the bay doors at the front of the coach first then work your way to the back. Then move to the opposite side of the coach starting with the front again.

Tip: If the measurement is not landing EXACTLY on a 1/16th inch mark. You must round DOWN to the nearest 1/16th.

Step: 3

Measure Door Height & Width

Measure the height of the bay door from the bottom edge to the top edge, recording the measurement. (Be very precise in your measurement.)


Measure the width making sure to always measure on the flattest surface. Never on a rounded corner If the door's edge is rounded, measure from the point it becomes flat, not from the end of the rounded edge. If not done correctly, your measurement will be too long.

Tip: When measuring the width. Do not start your measurement across the radius. Move your measuring tape up to the point where the door becomes a flat surface. Use this rule for all doors.

Tip: The bottom of some doors will have a radius. Use a flexible measuring tape to get the full height of the door by starting at the bottom and wrapping the measuring tape tightly around the radius then measuring up to the top of the door.

Step 4:

Measure Latch/Handle

This is not always a necessary step depending on your coach and what armor you have chosen.


Measure the height and width of the first latch/handle. On each door the distance from the top of the door to the center of the lock and handle. Also measure from edge of the door to the center of the lock and handle. Record these positions precisely.

Tip: Stay consistent with which side of the door you measure your latches from. We reccommend measuring from the side closest to the latch/handle

Step: 5

Measure Departure Angle

Towards the back of the coach are door(s) that may have a departure angle (front corner of the door is taller than the back corner) at the bottom of the door. To measure correctly, measure the height of the door on both the shortest and tallest points. Use the same reference point when measuring both corners. This will help us determine the departure angle of that door.

Step 6:

Double-Check Measurements

If you are unsure of your measurements, re-measure to ensure accuracy. Accurate measurements are essential. Record all measurements clearly on paper.

Step: 7


Record all measurements and photos, then submit them for custom fitting.
