Important things to know:

- Lumber pattern is not guaranteed. This comes from raw lumber and varies in tint, shade, and grain. Small defects in the veneer also occur occasionally and we make a great effort not to use any lumber with serious flaws.

Are the edges visible on this cabinet?

The edges are covered by edge banding in the prefinished maple option, but raw edges are visible in any of the bamboo options. 

    If you plan on painting:

    • lightly scuff the entire surface of the cabinet that you plan on coating with 120-180 grit sandpaper.
    • Apply 2-3 coats of primer prior to applying your main coat.
    • Always apply a finish when you're happy with the paint to get a long lasting appearance.

    If you plan on staining bamboo:

    • Sand the surface on all faces with sandpaper traveling with the grain of the wood.
    • Apply stain very cautiously to a section of the cabinet that will not be visible to gage the volume and pressure you need to achieve the look you want.
    • Apply stain evenly with a rag, sponge, or spray gun until all surfaces are coated.
    • Please note that overlapping surfaces may make the stain darker on the overlapped areas.
    • Always apply a finish when you're happy with the stain to get a long lasting appearance.

    The Promaster only has one beam in the front to mount to. What should I do?

      Our promaster upper cabinets should mount to more than one beam, but as noted it's not long enough to hit two. For this reason, we recommend using fasteners liberally to join the cabinets to the ceiling panels. We've seen great success from using standard wall anchors designed for studs (The metal variant) or other wall anchors designed to open up and expand behind the ceiling panel.

      It's also recommended to use rivet nuts or similar anchoring method to join the cabinets to the horizontal beam running the length of the vehicle along the bottom/back of the cabinet.

      I took a chance on ordering from Serg Supply. It was a good investment, while we had a little hiccup in shipping, they quickly fixed it to this customer satisfaction. These high-graded, simply elegant and yes finely crafted storage spaces add to the elegance in my van.

      Ordered three cabinets for our new Sprinter and we were not disappointed! Beautiful craftsmanship, quick turn-around time, communicative seller and more. The cabinets came pre-drilled, instructions, and a drill bit to use that matches the screws....little details that mean a lot!
