"An excellent product for DIY fence jobs. Saves you from cutting out notches in the posts or aligning the pre-notched posts accurately. Gives you a little room for tweaking the fence as you go. Nice and cheap to buy too."
"I use these a great deal when building this type of fence, its quick & easy to use, plus if you want to replace a broken rail, you just un-screw it & fit a new one in no time at all, unlike traditional morticed and tennon arris rail construction."
