The Zareba WP22 Multi-Groove Wood Post Ceramic Insulator doesn't come with washers included. From what we've gathered, some folks have mentioned that this could be a bit of a snag depending on how you plan to install them. If you think you'll need washers for your setup, you'll have to grab those separately.

Even without washers, these insulators are made to attach electrified wire to wood posts without letting energy escape into the post. It's something the manufacturer highlights in their description. They're compatible with steel, aluminum, and poly wire, and they have a smart multi-groove design that helps prevent arcing, which is pretty important for keeping your electric fence working safely.

According to our research, these ceramic insulators are tough and last a long time, especially when you stack them up against plastic insulators. People have pointed out that their fences stay strong and do a good job of keeping livestock like horses contained. This kind of feedback really underscores how reliable the Zareba WP22 can be in actual farm scenarios.

When it comes to cost, the Zareba WP22 is seen as a solid option by many, especially compared to what's out there at local farm supply stores. The missing washers might be a small hassle, but most folks think that the performance and price more than make up for it.

In the end, while this insulator gets high marks for its insulating power and bang for the buck, make sure it's the right fit for what you need. Thinking about whether you'll need extras like washers will help you get the best setup and performance from your electric fencing.
