INSTALLATION GUIDELINE

Installation Steps for Concrete, Lightweight Concrete and Metal Deck

  1. Using the proper size carbide bit (see chart) drill “a pilot hole at least 1” deeper than anchor embedment.
  2. Using an electric impact wrench, or socket wrench (hand install) insert anchor into hole and tighten anchor until fully seated (do not over tighten).

Installation Steps for Hollow or Grout-Filled CMU (3/8″ and 1/2″ diameter)

  1. Using a 5/16″ (for 3/8″ LDT) or 7/16″ (for 1/2″ LDT) carbide tipped bit, drill a pilot hole at least 1″ deeper than anchor embedment.
