Good product, fast shipping By Charlie

Very satisfied with the quick shipping. Using these on my home garden against rabbits, stringing the electric fence wire is a snap pun intended .. so fast and easy to install. I would like to see the bottom wire clip a little lower to prevent the smaller rabbits from going under the bottom wire. Where the ground has a few high spots, my solution to this was to dig a small depression so that the post foot bar is slightly below ground level but not enough to permit the wire to touch the ground. I would buy more if/when I need more.

White 4 Foot Step-In Fence Posts By Berry
Purchasing the posts was easy, volume discounts spelled out, free shipping (if over a certain dollar value), and shipped on time. The ease of purchase, the value and expectations of product and the follow-up more than met my expectations.

I wanted these to use in my garden for my tomato plants. The cages you buy in the stores are usually too small to contain the plants once they take off growing. So I used these around them then attached green gardening tape to them where the tomato branches were heaviest as they were growing. It makes the support custom to each plants need.

Q.How well do these hold up over the years? Do they wear down easily in the sun, become brittle etc...?

This product is made to last as it is constructed with durable polypropylene and steel.

Q.Is the 4 ft measurement including the spike so really just maybe 3.5 ft above ground?

The portion that sticks out of the ground is 38 inches. The entire post is 48 inches.

Q.What is your suggested spacing for theses posts? thanks in advance Brad

Posts for electrical fencing are typically spaced 12-20 feet apart. The spacing may vary depending on the animals being contained, terrain, wire type, and personal preference.
