Choose Your Strap Length

Need Help Choosing a Repair?

Which repair should I choose?

Start with the joist type, damage location and dimensions, and available installation space. Compare the applicable product requirements; repair products are not interchangeable for every condition.

Are solid-sawn and engineered I-joist repairs the same?

No. Choose a repair intended for your joist type. Engineered I-joist web and flange damage require the corresponding product or project-specific engineering.

What information should I send for help?

Send the joist type, actual depth, span, spacing, damage dimensions and location, and clear photographs. Include nearby utilities and any installation access limits.
