Installation tips

  • 1.Requires SDS-Max rotary hammer for 7/8" hole — SDS-Plus struggles at this diameter
  • 2.Setting tool must be rated for 5/8" drop-ins — do not use smaller setting tools
  • 3.Engineer specification required for all overhead applications
  • 4.Used with 5/8-11 threaded rod — standard for heavy structural suspended systems
  • 5.Inspect setting tool condition before use — worn tools lead to under-set anchors
