Nope — order first, measure later. Once your order is placed, we'll email you a simple measurement form with instructions and a short video. Submit your dimensions and a few photos, and we confirm everything before fabricating. You won't be locked into measurements you're unsure about.
Very accurate — to 1/16 of an inch is ideal. That's what makes the fit custom. Don't worry, our measurement guide walks you through exactly what to measure and how.
Lead time is approximately 2 weeks after your measurements are confirmed. We build each kit to order, so we don't keep pre-cut inventory. Once shipped, your kit travels via USPS Priority Mail. You'll receive a tracking number as soon as it's on its way. Free shipping to anywhere in the contiguous USA.
In the unlikely event that this happens, we will make it right. Every kit is backed by our 100% satisfaction guarantee. If the fit isn't perfect, we'll remake your kit at no charge or issue a full refund. No runaround, no restocking fees. Just email us and we’ll take care of it.

Step-by-step install videos are included with every kit. Most customers complete installation in 30 minutes or less, even with no prior experience.
Our kits are made from high-quality metal components for durability and longevity.
