An Oldie but a Goodie, Modern Fence is now making Stainless Steel or Galvanized Rail Lock Brackets. Our Vinyl/PVC Rail and Post Lock Bracket is made of pre-galvanized mild steel and has multiple uses. Stop screwing right into your rail and possibly causing it to bulge or even cracking your vinyl post with our new rail bracket. Slotted holes allow for contraction and expansion of the Vinyl due to weather. Use on middle post and end post to safely secure your rails.
