What to know before ordering.
Check your opening first
Have the finished top/header in place before measuring. Measure at the top, not at floor level.
For unusual openings or a production thickness above 8 inches, contact us before ordering.
Ask about your opening →Finish it into the wall
Dry-fit and attach the forms, reinforce the seams with drywall tape, then apply joint compound, sand, prime and paint.
For non-structural indoor openings only. Follow the labels for all finishing products.

A few useful answers.
What do I need to measure?
The exact width at the top of your doorway, plus the smallest wall thickness from six readings at the two upper corners.
Open the measuring guide →Should I subtract the finishing allowance myself?
No. Enter the actual readings. The order card subtracts 1/8 inch from wall thickness and rounds the production thickness to the nearest eighth. It does not subtract from your doorway width.
Does the kit arrive looking like the room pictures?
The room pictures are interior visualizations of a finished result. Your kit contains the arch forms; you still need to attach, blend, prime and paint them.
When will it be made and shipped?
Kits are made to order in Alberta. Production takes 3–5 business days, plus delivery time. Shipping is CAD 29 per order within Canada and CAD 39 internationally.
Prefer just rounded corners?
