SOPREMA Sopracant MB Cant Strip, 1.25 in. or 2.25 in. Profile, Boxed
Soprema Sopracant MB cant strips form the 45-degree transition at wall and curb bases where the membrane turns up, preventing sharp bends in modified bitumen flashing. Available in 1.25 in. x 1.25 in. and 2.25 in. x 2.25 in. profiles, each box provides 78.7 or 39.3 linear feet respectively, sold as a boxed unit.
Key Features:
- 45-degree transition: Cant strips create the angled transition that eliminates sharp membrane bends at base details.
- Two profiles: Offered in 1.25 in. x 1.25 in. and 2.25 in. x 2.25 in. cross-sections.
- Boxed lengths: The 1.25 in. profile delivers 78.7 linear feet per box; the 2.25 in. profile delivers 39.3 linear feet per box.
- MB system ready: Designed for modified bitumen (MB) roof assemblies at walls, curbs and base flashings.
- Efficient handling: Boxed packaging keeps strips organized and easy to stage on the roof.

Coverage & How Much You Need:
One box of the 1.25 in. profile provides 78.7 linear feet of cant strip and one box of the 2.25 in. profile provides 39.3 linear feet. Measure the total perimeter of walls, curbs and other flashing bases, then divide by the box coverage and add waste for miters and field-cut ends.
Fit and Compatibility:
Intended for use with Soprema modified bitumen membrane systems at flashing bases, walls and curbs. The 2.25 in. profile suits larger membrane flashings; the 1.25 in. profile suits smaller base details, and both install under the base flashing ply.

Q: Where is cant strip installed?
A: It is placed at the 90-degree junction of the roof deck and wall or curb so the membrane flashing turns at a gradual angle instead of a sharp bend.
Q: Is it for modified bitumen only?
A: The Sopracant MB line is intended for MB roof assemblies; confirm system compatibility with your membrane manufacturer's details.
Q: How do I size my order?
A: Add up the linear footage of all flashing bases, divide by the per-box coverage for your chosen profile, and add waste for cuts and miters.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Always install cant strip before the base flashing ply so the modified bitumen turns smoothly up vertical surfaces; skipping it invites stress cracking at the bend. Choose the 2.25 in. profile where flashing height and detail size call for a wider transition. Miter and field-cut strips to fit inside and outside corners, and keep the run continuous along walls and curbs. Follow the membrane manufacturer's detail drawings for securement.
Install cant strips only on a clean, dry, properly prepared substrate and follow the roof system manufacturer's detail drawings for flashing transitions.
Order Soprema Sopracant MB cant strips to complete a smooth membrane transition at every flashing base.
