Frederick Solid Brass Cabinet Knob

Decorative resin covers are designed for wall and ceiling applications only — they are not rated for floor use. They're lightweight enough to mount safely overhead and decorative enough for walls where you want more visual detail than a stamped metal grille. If you need a floor register, our wood, metal, and cast iron options are built to be walked on.

Resin covers don't rust like metal, don't splinter like wood, and are significantly lighter than either — which makes them ideal for ceilings. They're formulated to handle the thermal cycling of central air and heat, so they won't warp or crack from temperature changes. Urethane resin is also stable in moisture-rich environments like bathrooms, where metal can corrode and wood can swell.

Yes — unfinished resin covers can be painted to match your walls or trim. However, covers that have already been painted at the factory are non-returnable. If you plan to paint, order an unpainted cover, apply your chosen color after testing on a sample, and install once dry. Standard spray paint adheres well to resin; no special primer is required for most colors.

Yes. Our decorative resin covers are available in standard sizes and hard-to-find dimensions — the same custom sizing program that covers wood and metal also applies to resin. If your duct opening doesn't match a listed size, contact us with your measurements and we'll confirm what's available. Allow approximately 6 weeks for custom resin orders.
