MTB Supply 39" White Heavy-Duty Step-In Pigtail Fence Posts — 10-Pack, Insulated Clips & 7" Two-Prong Foot

These 39-inch white heavy-duty pigtail step-in posts from MTB Supply are durable, insulated metal stakes designed to hold up to three strands of electric wire, polytape, or polywire for temporary fencing and animal containment.

If you need a portable, sturdy fencing solution for rotational grazing, temporary paddocks, or short-term yard protection, these 39" pigtail posts provide a reliable balance of rigidity and portability. Each post measures 39 inches long with 32 inches above ground, includes a welded two-pronged 7" foot for secure ground anchoring, and features an integrated insulated pigtail clip to hold wire, rope, or polytape. Sold as a pack of 10, they’re intended for quick setup and repeated use in gardens, pastures, and job sites.

How do these pigtail posts perform on hard or compacted ground?

The welded two-pronged 7" foot gives the post a stable base that resists wobbling and twisting in firm soil. For especially compacted or rocky ground, driving the post slightly at an angle or pre-loosening a small pilot hole with a probe or bar improves insertion and long-term stability.

• 7" two-pronged foot distributes force to reduce sinking and tilting
• Steel construction for strength against bending
• Step-in design speeds installation without post drivers

Can these hold multiple conductors like polywire, polytape, or steel wire?

Yes — the insulated pigtail clip is sized to retain up to three strands of conductor at different heights, keeping them separated and secure. The pigtail works with common temporary fence materials including 3-, 6-, or 9-strand polywire systems and polytape, so you can configure tension and visibility according to your animals’ needs.

• Holds up to three strands of wire or rope safely
• Insulated clip reduces grounding and helps maintain charge
• Compatible with standard polywire and polytape widths

How long will these posts last with repeated use and exposure?

Constructed from steel with a protective white finish, these posts are built for repeated setup and takedown in seasonal or temporary applications. While they are heavy-duty for step-in posts, longevity depends on exposure to moisture, salt, and mechanical wear; rinsing and drying after wet conditions and storing indoors when not in use will extend service life.

• Steel body resists bending under typical loads
• White finish improves visibility and helps reduce UV fading of attached tape
• Best practice: clean and store between seasons for longer life

What installation tips help keep the fence effective and safe?

Place posts at consistent spacing and ensure the welded foot is fully engaged in the soil for consistent line height and tension. Use a cordless driver or hammer only when necessary; step-in posts are designed for hand pressure but can be started with a mallet for very hard ground. Keep conductors properly insulated and tensioned to avoid sagging and to maintain visibility for animals.

• Space posts according to animal type and conductor used (closer for smaller animals)
• Start posts at a slight angle in rockier ground, then straighten for best hold
• Regularly inspect clip connections and tension to prevent sagging
