Planning Guide

Plan the right fit before choosing

Start With the Masonry Material

Choose short or long shields based on the application

Short lag shields are identified for harder masonry materials and can help reduce drilling time. Long lag shields are identified for softer or weaker masonry materials, where they provide increased strength. Product descriptions represent use in mortar joints, poured concrete, brick, concrete block, and concrete.

  • Use short shields for harder masonry materials.
  • Consider long shields for softer or weaker masonry materials.
  • Confirm that the intended material matches the product’s stated application.
Match the Anchor to the Job

Review size, anchor design, and grip action

Available sizes represented include 1/4 inch, 5/16 inch, 3/8 inch, and 1/2 inch options, with listed shield lengths including 1 inch and 1-3/4 inches. Two-piece shields create an anchor point for lag screws, while selected medium-duty steel shield options are designed to develop full grip as the lag screw is tightened.

  • Match the listed shield size to the application requirement.
  • Choose a listed long design when the application calls for an extra-long shield.
  • Review whether the product is described as a two-piece anchor or a medium-duty, grip-on-tightening option.
Plan the Installation Quantity

Select a pack count that fits the scope of work

The represented products are offered in 25-, 50-, and 100-piece packs. For certain two-piece shield options, installation is described as finger pressing or lightly tapping the shield into the drilled mounting hole.

  • Use the listed pack count to plan for the number of installation points.
  • Drill the mounting hole before placing shields described for finger-pressure or light-tap installation.
  • Tighten the lag screw where the product is designed to develop grip on tightening.
