About this item

  • Perfect 3.5"x3.5" Fit:Designed for standard US 4x4 lumber (true size 3.5"x3.5") . Prevents wobbling & returns – engineered for snug insertion of pressure-treated pine, cedar, or composite posts.
  • Prevent Rot:Raised base lifts wood posts above concrete/wood floor. Blocks moisture damage from rain, sprinklers, or snow – critical for decks, fences, and outdoor structures.
  • Heavy-Duty Steel: 2mm thick solid steel with full welds supports 200+ lbs. Black powder-coated finish resists rust in coastal/high-humidity areas. Outlasts flimsy zinc-plated competitors.
  • 3-in-1 Mounting Kit: Includes concrete wedge anchors (M8x60mm), wood deck screws (#14x2"), and self-tapping post screws. Pre-drilled holes align perfectly – no drilling.
  • Versatile: Ideal for deck footings, privacy fences, pergola columns, mailbox posts, and gazebos. Friendly design for residential/commercial use.

These post brackets should help to protect the wooden posts from water damage. They seem like they will do the job with our railing posts and can be mounted to the deck as well. Hole are provided for bolts to mount to the decking. The black powder coating should help to protect the metal brackets.

The size is incorrect. Not consistent with the description, there is a fake weld at the bottom that has cracked. Not sturdy. Very dangerous.

Thick gauge metal post base. Great for decks. Heavy thick gauge metal will last for years. Looks clean and squared away once installed. Easy to use and fits 4x4 post as expected. Great price for a quality item.

The fit and finish on these post bases is top notch! The concrete anchors that are supplied with them are kind of cheesy though. The nuts don't fit well and four of the twenty four anchors pulled out of very solid concrete. The next time I install these post bases I will buy my own anchors.

Heavy gauge steel. Allows water to drain out the bottom so post does not stay wet. Excellent finish. Well built. Highly recommend.
