Build your own rugged and heavy duty PostHugger™ Pergola, Double Pergola, shop/garage/CNC table, or deck with our USA made 1/8″ steel corner brackets!

Also great for fixing/reinforcing the one you already have! These are not flimsy/bendable metal. We make them using 1/8″ thick steel – a single corner bracket weighs 6 pounds – – strong enough to take what you throw at it (or what you throw it at!), but not so heavy where they are hard to work with. And all our PostHugger™ Brackets & metal artwork products are Made in America with American-Made Steel!

We are the original designer of the PostHugger™ brackets, which may be copied, but never equaled! 🙂 If you find a PostHugger™ knockoff, give us a chance to meet or beat their price.

We get a lot of questions about how to build a double pergola (one with six legs) like you may have seen in one of our photos – they use the following:

  • 4 Outside Corners
  • 2 Flat T
  • 8 Bent L Inside Corners
  • Optional 6 sets of our Two-Piece Post Bases if you are not setting your posts in concrete.

Our brackets can be installed using any 1/2″ wood lag screws or 1/2″ through-bolts.  If you use lag screws, we recommend 1/2″ x a minimum of a 2.5″ long lag bolt, with longer bolts adding more strength. WOOD AND BOLTS/LAG SCREWS ARE NOT INCLUDED WITH OUR BRACKETS; you can pick them up at your local home improvement and hardware stores. Lifestyle customer photos depict build/use variations only.

Our Brackets Product Line includes:

  • Outside Corners – Used on outside corners to join/attach two incoming horizontal posts on top of an upright/vertical post.  The holes line up with Bent L’s if you want to use them on the inside.  They also work with the Double Inside Corner.
  • Flat T Brackets – Used to join/attach two incoming horizontal posts which are resting on top of an upright/vertical post.  The holes line up with the Bent L’s in case you want to use them in making an inside corner on the opposite side of your Flat T.
  • Bent L’s – Used as an inside corner, either alone or in conjunction with an Outside Corner to make a steel/post/steel sandwich for aesthetics and/or additional strength.  The holes also line up with our Flat T’s.
  • Double Inside Corners – The bottom part of this bracket attaches to the inside corner of an upright post, which then allows each ear on the top part of the bracket to go under horizontal posts coming in from the left and right sides.  The holes work with an Outside Corner — for the upright, they are aligned, so you can bolt through and make a steel/post/steel sandwich and for the two incoming horizontal posts, the holes are offset so they do not collide. 
  • Flat L’s – Used to join other parts of your design.
  • Two Piece Post Base – Used to bolt a post to concrete or other suitable surface.  If your post is going up against a wall or other flat surface which would interfere with having four feet, you will want to use either our Half-a-Post-Base, our 3-Sided Post Base (which has three feet) or our Full Post Base (which has just two feet) so that your post can be closer to a wall.
  • Half a Post Base – This bracket is just one half of the Two Piece Post Base, for those who only need one (or another odd number).
  • Three-Sided Post Base – Similar to our other Post Bases, but with three sides/feet.
  • Full Post Base – Similar to our other Post Bases but with fours sides and just two feet (on opposite sides).
  • Legless T™ – This bracket is the same dimensions & placement of bolt holes as the “T” – just without the bottom “leg” of the “T”! It measures 5.5″ x 16.5″ for a 6×6 post, and 3.5″ x 10.25″ for a 4×4 Post.
  • Flat X™ Bracket  – 90 degree cross angle brackets to provide extra, heavy duty support to new or existing DIY builds & structures.
  • Flat Y™ Bracket – Y-shaped or 45-degree double-knee design, to provide extra, heavy duty support to new or existing DIY builds & structures such as where you have a structure post with two kicker sections coming off of it from each side.
  • Flat Knee™ – This knee brace bracket sits flush against the outside of a knee joint.
  • Bent Knee™ – This knee brace bracket is for use where you have a post coming in to meet another post at a 45° angle and want a bracket in the knee bend itself

Please note that unless you choose the powder coated option, these ship as unfinished steel. You can either paint them the color of your choice, finish them with a clear coat, or allow to achieve a natural rust patina over time.  If ordering our powder coated brackets, your order may  take an additional day or two to work its way through our powder coating process, depending on our inventory at the time of your order.
