Raised Garden Bed Anchor Joints

Raised Garden Bed Anchor Joints

A very innovative accessory, that we could use for building raised beds is an anchor or corner joint. This is a devise that has slots for the timber frames and holds the sides and ends of our raised bed frame together. It is for sure, a great piece of inventive technology and will make the process of building raised garden beds very simple. The anchor joints or corners as they are sometimes known, are made from hard durable plastic or metal steeel. The steel variation is a little difficult to source and is obviously more expensive that the palstic pvc model. The whole idea of these devices to make the process of raised bed construction very simple and speeds up the whole assembly of these bed frames.

These anchor joints are available online from the usual sources and some garden centres and hardware wholesalers, may stock these also. The flanges on the anchor joints have pre-drilled pilot holes which again makes our assembly and construction job that bit easier. All we need then is the lengths of lumber or wood for the sides and ends of the bed. There is a long centre stake that is pushed into the soil, this will ultimately hold the whole raised bed frame firmly in place. The idea would be to either construct the whole frame together, ie the corner joints and the timber sides and then position into our selected location. The other method would be to insert the anchor joints into the ground at the correct measured distances, then add the timber boards and screw the whole lot together.



Anchor Joints for Raised Beds


Overview of raised bed garden anchor joints;

  • Retailed in pack of two,
  • Cost – $18 plus shipping,
  • Made from durable UV plastic,
  • Makes building raised beds simple,
  • Flexible and movable flanges,
  • Can accomodate 1″ or 2″ boards,
  • Pre-drilled pilot holes,
  • 10″ Ground Stake for strength and robustness,
  • No corner posts required,


As we can see from the above images of these corner joints, its now relatively easy to make and assemble raised beds with these devices. If we purchase the anchor joints locally or online, we may have the timber in our garage or shed, so therefore this system would make the assembly of raised beds very inexpensive. Like we mentioned above, just place the joints in the ground, add the timber lengths, screw into the hinges and we are done.

Steel anchor joints overview;

  • Packs of four,
  • Black powder coated steel,
  • Pre-drilled pilot holes,
  • Very easy to install,
  • Can accomodate boards up to 12″ in height,
  • Creates a professional look and finish,
  • Can be re-sprayed if desired to suit,
  • Cost – $30 plus shipping


These are a different system to the plastic model, in that we don’t have an anchor stake that inserts into the ground. This devise is basically a corner strengthing accessory, in which we screw the sides and ends of our bed frame planks together with the help of this corner bracket. As per image above, we see that its somewhat different in design, yet at the same time will ably assist us in our raised bed construction assembly. Ideal if we are locating our raised beds on a hard surface or balcony terrace, where we would not need to insert a post into the ground.

Other types of corner angle joints;


There are lengths of angle iron that we could purchase at a hardware or ironmonger stores, which if cut to the height of our raised bed boards, would do the job for us just as good. We would not need any carpentry skills to make this happen, just a small degree of handyman or maintenance savvy. We would need to have a hacksaw, electric or cordless drill to make the holes and we would also need to purchase some screws to attach the planks to the angle corner joints.

These joints are also available online and are equally suitable for the making and construction of our raised beds. As we can see from the image these are very basic accessories, they come in a packet of 4 and again have pre-drilled holes. These corner joints are very strong, durable, robust and will support raised bed boards of up to 20″ in height. The joints are again made from powder coated steel and will last for ages.

This overview on raised bed anchor joints is to assist and inform people who are interested in building raised garden beds.

It will hopefully make the job of constructing raised beds a bit less laborious and ultimately less expensive.

  2. Phil,

    What a great tip – these things would make constructing a raised bed so much simpler – it’s often the simple things that make the real difference and I hadn’t thought about looking for corner pieces like this.

    Just two questions if I may…

    – How important is it to ensure the ground is level (I.E., not on a slope)?
    – Are you limited to square beds, or can these be used for, say, triangular or hexagonal beds?

    Many thanks,


    1. Hi there Al,

      Many thanks for reading this post on anchor joints for raised beds. Yes, as you rightly pointed out, these corner joints would make constructing raised beds much more easier and simpler.

      As far as the raised beds on a slope, that situation is not ideal, the moisture in the beds would evaporate much faster and would be a problem going forward. Unlesss you were able to dig out one part of the slope and attempt to integrate the bed frame into the slope, that may help.

      These anchor joints would definitely assist you with the triangular or hexagonal beds. The flanges are movable, so therefore you can turn them in any direction that you wish.

      Here’s hoping that this information is useful and informative.

      Happy gardening,

      Cheers  Phil Browne
