Frequently Asked Questions

• Are these rods code compliant? Yes. When used with Simpson epoxy systems, these rods meet ICC-ES ESR-2508 (SET-XP) and other ICC criteria for cracked and uncracked concrete.
• Do they work with any epoxy? Simpson all-thread rod is specifically designed and tested for Simpson adhesives. Using non-Simpson epoxies may void performance warranties or ICC approvals.
