Custom wooden arch opening frame by ModuleARCH

Arch Opening Frames

Transform any standard rectangular doorway into an elegant arched passage — without tearing out framing. Our pre-formed arch frames install directly into existing openings, giving you the look of a true arched entry with minimal work.

How It Works

An arch opening frame is a pre-formed wooden insert designed to fit inside a standard rectangular door or cased opening. It creates the visual curve of an arch while the surrounding structure stays untouched. You simply specify three measurements in our configurator:

  • Opening width — the width of your existing opening
  • Arch start height — where the straight sides end and the curve begins
  • Arch apex height — the highest point of the arch

The difference between the start height and the apex height determines the curve's depth. A shallow difference creates a subtle eyebrow arch; a larger difference creates a dramatic Romanesque curve.

Why Choose an Arch Frame

No Structural Changes

Unlike a true arched opening, an arch frame doesn't require modifying your header, studs, or drywall. It inserts into the existing opening and can be removed later if needed.

Fully Custom Dimensions

Every arch frame is made to your exact measurements. No off-the-shelf sizes to compromise on — specify width, curve start, and apex to the inch.

Quick Installation

The frame arrives pre-formed and ready to mount. Installation is straightforward for any experienced carpenter or handy homeowner.
