DeWitt 6 In. x 1 In. 11 Ga. Steel Landscape Anchor Pins 75-Pack

The DeWitt 11-gauge steel anchor pins solve the fabric migration problem that plastic stakes can’t touch. At 6 inches long and 1 inch wide, these U-shaped steel staples drive deep enough to hold landscape fabric through Montana’s freeze-thaw cycles and spring winds. The 75-pack weighs 4 pounds total — heavy-duty hardware that contractors trust for permanent installations.

When Steel Beats Plastic

The 11-gauge thickness provides the holding power that matters in challenging soil conditions. These pins feature angled ends (chisel tips) for faster and easier installation in various soil types, from the clay valleys to rocky mountain terrain. The flat-top/U-shape design ensures secure anchoring of fabric edges and seams.

The chisel-tip design earns its keep when driving through compacted gravel driveways or glacial till. Sturdy enough to penetrate thick fabrics and compacted soil, these pins handle commercial-grade landscape fabrics without bending. Once installed, they’re designed to be flush with the ground to prevent tripping or mower interference — critical for maintained commercial properties.

The non-galvanized steel construction means they’ll rust, but that’s actually an advantage in many applications. Some users prefer rust for better soil grip — the oxidation creates mechanical bonding with surrounding soil that smooth galvanized pins can’t match.

Applications and Installation

Primary applications include permanently anchoring landscape fabrics and weed barriers, securing ground covers, erosion control blankets, and jute netting. They’re equally effective for holding down drip irrigation tubing, soaker hoses, and sprinkler lines. For sod installations, these pins fasten sod and turf to soil for rooting stabilization.

Installation follows standard practice:

  • Position the pin over the edge or seam of the landscape fabric and insert the angled tips into the soil
  • Drive the pin until the top is flush with the ground surface
  • For optimal results, space pins every 3-5 feet along edges and seams
  • In very hard soil, using a pilot hole or a heavy mallet is recommended to prevent bending

Secondary uses include securing tent lines, deer fencing, and light garden structures — handy for temporary installations where the 6-inch depth provides real holding power.

For contractors handling large projects, DeWitt offers bulk alternatives: 500-pack (AP500) and 1,000-pack (AP1000). The 75-pack hits the sweet spot for typical residential installations, while commercial crews appreciate the bulk options for efficiency.

The pins work with all types of DeWitt landscape fabrics (Pro-5, Weed Barrier, etc.), third-party weed control fabrics and burlap, plastic and rubber drip irrigation tubing, and erosion control mats and turf/sod.

FAQ

Q: How do these compare to 9-gauge staples? 9-gauge staples are thicker and heavier duty for extremely hard or stony soil. The 11-gauge pins handle most Montana soils effectively while being easier to drive.

Q: Will rust affect their performance? While they rust quickly as they are typically non-galvanized, some users prefer rust for better soil grip. The rust creates additional friction that helps lock the pin in place.

Q: Are 6 inches long enough for sandy soil? The 6-inch length may be insufficient for very loose or sandy soils. For extremely loose conditions, consider the 9-gauge options or increase pin density.

Q: Do they work with heavy commercial fabric? These pins are sturdy enough to penetrate thick fabrics and compacted soil. The chisel tips help pierce multiple fabric layers without tearing.

Q: What spacing works best? For optimal results, space pins every 3-5 feet along edges and seams. Increase density in high-wind areas or loose soil conditions.
