 2-3/8″  Pipe and Post Collars, the better choice for privacy fence!

Upon our introduction of the first One-piece fully adjustable post collar for 2-3/8″ diameter pipe, Slip Mount offered many more benefits over the use of 1-7/8″ Pipe and collars.

  • 2-3/8” pipe has a larger diameter, this means more strength.
  • Offers better ground anchoring, more soils transfer up inside the pipe cavity during post driving, this adds more bottom weight.
  • 2-3/8” pipe offers an additional 24 more sq inches of side wall over 1-7/8″ pipe in contact with below ground soils for greater  grip and prevent’s pipe up lift during winter frost heaving.
  • 2-3/8″ pipe is more rigid, has less flex at the top of pipe, entire fence moves and wobbles less during wind.
  • 2-3/8″ pipe still allows 1-1/2″ of bottom rail insertion into a standard 5″x 5″ vinyl fence post.

How long has pipe driven fence systems been around, and when did vinyl posts come in? 

Pipe to fence post mounting techniques have been in use for the propose of fixing or attaching wood and other materials to an upright pipe driven into the ground dating back to the late 1800’s. It was not until the (PVC) vinyl fence industry grew in popularity and by the year 2000 a product became available in Canada with G. Elsasser’s patent. Specifically designed for installing a hollow vinyl fence post over an upright fixed pipe or tubing, Elsasser’s patent illustrates an X design having a square in its center. This design allowed a vertical upright pipe or tube inside the center cavity, once fastened a hollow vinyl fence post profile would sleeve over the outside, the X rib feature supported the inside walls of the hollow fence post. The design still allowed horizontal fence rails to penetrate inside the vinyl post through cut-outs without obstruction from the device.
