Arch forms only. Finishing and painting are required.
Check the fit
What to know before ordering.
Check your opening first
The two upper corners should be close to 90°. Bullnose edges and strongly uneven walls need a fit review.
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 smallest wall thickness from six readings at the two upper corners. You do not need to enter the opening width.
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.
