YCFERESY Electric Fence Screw-In Ring Insulators 100pc Black with Socket Tool — 2" Offset, UV‑Resistant

These YCFERESY screw-in ring insulators are heavy-duty electric fence fittings that secure and insulate electrified wire from wooden posts, supplied as a 100-piece kit with a free socket tool and gloves.

Keep predators and persistent wildlife out of gardens and pastures without compromising your fence’s electrical performance. The YCFERESY set includes 100 black screw-in ring insulators engineered to hold high-tensile wires about two inches from wooden posts, plus an installation socket and protective gloves. Built from reinforced plastic with metal reinforcements, these insulators are made for long outdoor life in sun, rain, and seasonal temperature swings.

How do these insulators prevent electrical shorts on wooden posts?

Each ring positions the energized wire away from the post surface to stop contact and shorting. The slotted ring design cradles the wire securely while the insulating material resists current leakage and moisture intrusion. Installing them at consistent spacing keeps the circuit intact and reduces power loss.

• 2-inch offset keeps wire clear of the post
• Angled slot holds wire to prevent slipping and abrasion
• High insulation resistance reduces leakage in wet conditions

How quickly can I fit these to my fence line?

Screwing these insulators into wooden posts is fast when you use the included socket tool with a drill; it speeds installation and reduces hand strain. For best results, drill small pilot holes first so the insulators thread in smoothly and align uniformly along the post. One-person installs become practical for long runs when using a power driver and the socket adapter.

• Includes one socket tool compatible with standard drills
• Recommended pilot hole minimizes splitting and eases threading
• Pack of 100 supports multi-line fences or multiple paddocks

What wire types and loads are compatible with these rings?

These insulators are designed for a wide range of conductive fencing materials including high-tensile steel, aluminum, polybraid and polywire. The slot geometry reduces wear on braided strands and offers stable contact for both low-impedance and standard fence energizers. They are not rated as a structural post anchor but as electrical isolators and wire supports.

• Works with steel, aluminum, polywire and polybraid
• Suitable for typical livestock and garden energizers
• Best used on wooden posts only, as recommended

Will they withstand outdoor weather and animal pressure?

The YCFERESY rings combine thickened plastic and metal reinforcement to resist UV degradation, freeze–thaw cycling and moisture. Their robust screw threads and snug ring slot reduce the chance of being dislodged by rubbing animals or strong winds. For high-traffic points, use closer spacing or heavier gauge wire for extra resilience.

• UV- and rain-resistant materials for long service life
• Threaded design holds tightly in wooden posts
• Included gloves protect hands during installation

Who is this for? This kit is aimed at farmers, gardeners, and property owners who use electrified fencing to deter wildlife and contain livestock, and who want a reliable, easy-to-install insulator solution. It’s especially helpful for DIY installers outfitting multiple fence lines, contractors maintaining perimeter systems, and anyone replacing worn insulators on wooden posts. Note: these insulators are intended for use with wooden posts and to maintain spacing to avoid electrical faults.
