Installation Tips
1.Hole must be oversized: 5/8" hole for 1/2" rod (25% larger than rod diameter)
2.Blow hole clean with compressed air, then brush, then blow again — 3-step cleaning is mandatory
3.Inject epoxy from the bottom of the hole — work upward to prevent voids
4.Do not load the anchor until epoxy has fully cured — gel time varies by temperature
5.Use ICC-ES approved epoxy systems for code-required structural applications
