Great product, but I had to modify it. I used it to run invisible fence around the perimeter of a chain link fence. Biggest issue was the screw. It either didn't want to bite, or, when it did, it wasn't very secure. Ended up buying #6 x 2" machine screws with nuts, and #8 washers. Feed the screw and washer through the hole, and into the screw hole of the bracket. Place a washer and nut on other end and tighten. It'll be much more secure after that.

If you are thinking that you can buy this package, screw them together, then install them you'd be mistaken. The supplier has either stamped the wrong size hole in the bracket or shipped these with the wrong size screw. Quality control was definitely napping when the supplier put these things together. If you want to use these you will either have to buy screws that fit or drill out the brackets to use the screw that came with the product. I think the supplier either needs to recall all of these or ship out the right size screw for the bracket to the vendors to give to everyone that purchases this product. Ignoring an issue like this isn't good for the supplier, vendor, or customer.
