Why the Trim Matters

The Finishing Detail

✦

Precision Match

Milled to match the Natural White Oak Harmony Series panels in species, finish, and tone. Where the panel ends, the trim picks up — a seamless transition that makes the overall installation read as intentional and complete.

⊢

Clean Edge Termination

Acoustic panels have raw edges at corners, doorways, and ceiling transitions. This trim covers those edges cleanly — no exposed PET backing, no raw wood, no visible fasteners. The professional detail that separates a finished installation from an unfinished one.

⊕

Easy to Cut & Install

94″ length fits most standard ceiling heights with room to spare. Cut to length with a fine-tooth saw or miter saw. Install with panel adhesive, brad nails, or finishing nails — the same tools used for the panels themselves.

🌲

Premium Natural White Oak

Natural White Oak slats bring warmth and honest wood character to any surface. The open, consistent grain of White Oak takes finish beautifully and pairs with virtually every interior palette — from raw concrete to painted millwork. A purpose-built companion piece — not a generic trim profile.

Planning Your Trim Quantity

Count the number of exposed panel edges in your installation — ends of runs, outside corners, transitions to adjacent surfaces, and ceiling or floor terminations. Each location needs one trim piece. At 94″ per piece, one trim covers most standard 8′ ceiling heights with approximately 2″ to spare. For 9′ or 10′ ceilings, join two pieces end-to-end with a scarf joint for a clean continuous line.

Installation

Step by Step

1

Measure & Cut

Measure the edge or corner you're trimming. Cut to length with a fine-tooth hand saw or miter saw. For corners, cut 45° miters for a clean inside or outside corner joint.

2

Dry Fit First

Always dry fit before applying adhesive. Check that the trim sits flush against the panel edge and the adjacent surface. Adjust the cut if needed.

3

Apply & Secure

Apply panel adhesive in a continuous bead. Press firmly and hold for 60 seconds. Supplement with 18-gauge brad nails for a permanent mechanical hold — set nails slightly below the surface and fill with matching wood filler.

4

Long Runs & Scarf Joints

For ceiling heights over 94″, join two trim pieces with a 45° scarf joint at mid-height. Stagger scarf joint locations across adjacent trim pieces so no two joints align at the same height.

Products cannot be returned without prior approval and must have a Return Goods Authorization (RGA) number. Under the following circumstances, products may not be returned for credit:

  1. Are marked on
  2. Are modified in any way
  3. Have been exposed to excessive sun or moisture
  4. Have sheetrock mud, primer, stain, "job site damage"
  5. Returned 60 days after invoice purchase date

Returns are F.O.B. Buyer and are subject to a 20% restocking charge. To receive credit for stock products, product must be received in re-sellable condition. Custom mouldings and custom woodcarvings are not returnable under any circumstances. If returned products are received damaged due to poor repackaging, no credit will be processed. It is imperative that items are not returned in their original packaging without a thorough inspection as more fill may be needed to boxes of carvings or additional wrapping for mouldings may be necessary to prevent return shipment damage. Please call  1-800-558-0119 and speak to our Customer Service Representative to request an RGA.

*Claims for packages marked "delivered" must be filed after 5 days and before 15 days from the date the package was marked "delivered." Claims for packages presumed to be lost (where the status is not "delivered") must be filed after 7 days (20 days for international) and within 30 days from the last checkpoint.

Shipping rates vary by product category — see the rate table on each product page. Residential LTL deliveries require capable help to unload. Inspect all shipments within 15 days and report damage immediately. Customer is responsible for all freight charges, including residential delivery fees and liftgate charges.
