Accordion Boot Installation Readiness Checklist Accordion Boot Installation Readiness Checklist Use this checklist to see if a Flexordion accordion boot is likely to work for your truck, camper, sleeper, utility body, audio blow-through, or custom pass-through application. 1. Opening Shape & Alignment Both openings are the same basic shape. Both openings are aligned with each other. Both openings have the exact orientation and perimeter size. 2. Corner Radius Corners have at least a 1 inch radius or a 45 degree transition. More is better. There are no sharp 90 degree square corners. 3. Flange / Mounting Surface Both openings have a thin wall or flange approximately +/- 1/8 inch thick, not to exceed 3/16 inch. The flange is fairly straight with few bends. The flange provides proper support around the opening. 4. Parallel Surface Check Facing walls are mostly parallel. Gap variation from top to bottom is within about 2 inches. 5. Perimeter Measurement Both openings have the exact outside perimeter measurement. Width, height, and total perimeter have been measured. 6. Gap Distance Measure the distance between the two mounting surfaces at the top and bottom of the opening. The largest measurement is used for boot selection. Top Gap: Bottom Gap: 7. Movement / Flex / Articulation Expected movement level: Minimal - highway use / rigid mounting Moderate - normal truck or camper use Extreme - off-road, frame flex, or heavy articulation For extreme movement, the calculator deducts 1 inch from the measured gap before recommending a boot size.
