Crownduit’s Removable Miterless Moulding System

The Crownduit® System combines a Removable Poplar Crown Moulding Raceway with a PVC mounting track. Crownduit® is ideal for wiring the Smart Home and allows for ease of serviceability with Telecommunications Installations. Crownduit® is a complete component system - no mitering, nails or putty required. Overlapping seam covers eliminate seams from opening due to expansion and contraction. Crownduit® Crown Moulding beautifies any room with the added advantage of a built-in wire chase for future wire management needs.

Removable Poplar Crown Moulding Raceway

Crownduit's faceplate and components are made from Poplar wood which is an eco-friendly raw material. Its fast growth rate and short rotation period allow it to meet human demand and can avoid the consumption of natural forests. Poplar has a tight, straight grain providing a smooth finish. USA sourced, manufactured and FSC certified.

PVC Wire Chase

Crownduit’s internal wire chase is made of Color Master CMR4240 NAT 01 ridged PVC compound. 57% of PVC is made out of chlorine, which is delivered from common salt that is abundant on earth. Therefore PVC contributes significantly to saving oil or gas, which are non renewable resources, in comparison to other plastics whose composition depends entirely on oil. Crownduit’s internal wire chase is self extinguishable, made from 100% pure virgin PVC.


This style of moulding has an inward sweep of crown called scotia or cyma recta, the Greek word for wave or upright (cove). The convex curve is called ovolo (ogee). It is derived from classic Greek architecture.

The style dominates American trim work from the Greek revival period (circa 1820s) onward. The cove and undulating ogee form a classic pair. The shape brings together two basic building blocks of profiles and would appropriately embellish the interior in most style houses/buildings.

Our moulding styles come with seam covers and inside and outside corners that are self aligning.
