SiliFine Ceramic Donut Fence Insulators 25-Pack WP36 White for Corner Wood Posts, Weather-Resistant Porcelain

SiliFine WP36 are white ceramic donut insulators sold in a pack of 25, designed to fasten and electrically isolate fence wire at corner wooden posts.

These WP36 porcelain corner-post insulators give a durable, weather-resistant anchor point for electric fence wire and polyrope on timber posts. Made from smooth, glazed ceramic, each unit features a centered hole for threading wire or iron ties and a compact profile that fits most post setups. The supply of 25 pieces suits medium to large projects or ongoing maintenance, and the neutral white finish blends with outdoor fencing without rusting or degrading from sun and rain.

How do these insulators attach to wooden corner posts?

Installation is simple and requires only basic tools. Thread an iron or fence wire through the central hole, wrap or tie the wire around the post, and secure the connection so the insulator holds tension while keeping the wire insulated from the post.

• Thread wire through the 0.44-inch hole for a snug fit.
• Use an additional tie or lead wire to fasten to the post.
• Can be mounted at corners or end-posts where extra pull occurs.

Will ceramic resist outdoor conditions and electrical load?

Ceramic WP36 insulators are chosen for their electrical insulating properties and resistance to weathering. The glazed porcelain surface slows moisture penetration and resists UV and chemical exposure, helping maintain electrical isolation and mechanical integrity over time.

• Glazed ceramic minimizes moisture absorption and fading.
• Withstands temperature swings without cracking under normal use.
• Maintains insulation between live wire and wooden post for safer fences.

What size are these donut insulators and which wires do they accept?

Each WP36 insulator measures about 1.65 inches in diameter and about 1.5 inches tall, with the center hole roughly 0.44 inches wide. That sizing accommodates common fence wires, iron ties, and small-diameter polyrope or tape used on garden, farm, and paddock fencing.

• Overall diameter: ~1.65 inches; height: ~1.5 inches.
• Hole diameter: ~0.44 inches suitable for wire and small rope.
• Compact form works on standard wooden posts without bulky hardware.

How many insulators do I get and can they cover a full fence project?

The pack contains 25 insulators, which is enough for many small to medium fence runs or as a substantial supply for repairs. For full perimeter fencing on larger properties you may need additional packs, but 25 provides a strong starting inventory for corners, ends, and repairs.

• Pack quantity: 25 ceramic insulators per order.
• Ideal for multiple corners, gates, and reinforcement points.
• Good stash for seasonal maintenance and neighbor-sharing.

Who is this for: SiliFine WP36 ceramic donut insulators suit homeowners, small farmers, equestrian facilities, and contractors who need reliable, long-lasting isolation at corner and end posts. If you install electric or polyrope fences on wooden posts and want a corrosion-free, compact insulator that’s easy to mount and keeps wire away from timber, this 25-piece set is a practical supply for installation and upkeep.
