White River Hardwoods · Urethane Moulding Accessories

Coupling Universal

SKU CMC1000 · 3-1/2″ P × 3-5/8″ H

Solid Urethane · Factory Primed · Made in the USA

A pre-formed coupling block that replaces the compound miter at a splice between two lengths. Butt the straight runs into it square, and the corner is done.

No Compound Miters · Factory Primed · Installs with the Matching Moulding

The corner is where crown installations go wrong. A cast corner block makes it the easiest cut on the wall.

Why a Corner Block

Two Square Cuts Instead of Four Compound Ones

Square Cuts Only

Straight runs are cut at 90° and butted into the block. No spring angle, no miter saw compound settings, no test cuts.

Profile-Matched

Cast from the same pattern as its moulding, so the relief, height, and projection line up without shimming or filling.

Factory Primed

Primed to match the moulding it pairs with. Paint everything in one pass after installation.

Forgiving of Out-of-Square Rooms

Walls rarely meet at a true 90°. A corner block hides the variance that a mitered joint would show.

Installation

Step by Step

1

Set the Block First

Position the corner block, check it with a level in both directions, and fix it with construction adhesive and two finish nails.

2

Cut Runs Square

Measure from the face of the block to the next block or wall end. Cut the moulding at 90°.

3

Butt & Fasten

Slide the run into the block, adhesive on the mating edge, and nail or screw into framing every 16″.

4

Fill, Caulk, Paint

Fill nail holes, caulk the block-to-run seam and ceiling and wall lines, then paint block and moulding together.

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.
