EXPANDING ANCHORS

Made in USA logo indicating bust anchors are made in the US using American steel

Expanding anchors are a key component in a number of different industries, particularly in telecommunications. These anchors make use of the soil around them — typically rocky or hard soil for these products — to help create anchor points and provide stability for structures, cables, and equipment.

The eight blade, one-piece top plate, deeply embossed for additional strength, expands upon impact into undisturbed earth to form a pyramid-shaped square. The 8-way expanding anchors retain their shape under extremely heavy loads due to the support of the eight blades by the base plate. This provides you with an unparalleled level of strength and stability.

The expanding anchors are coated with a special asphalt paint to protect them against corrosive soil conditions. They are also available in hot dip galvanized. Check out the specs below and then give us a call today to start ordering or get more information!

To ensure you get the most use out of your expanding anchors, they should only be installed by certified Grip-Tite installers. To find the certified installers in your area, head over to our “find a certified installer” page. If you run a home improvement business and are looking to become Grip-Tite certified yourself, see our “become a certified installer” page.
