Very sturdy, well-constructed, but flexible panels difficult to bend into tight radius

I purchased two flexible panels to make a ~5-foot diameter circle and rigid panels to make a separate 24"x ~19' rectanglular box. The rectangular box was straightforward to put together and is very sturdy. I expect it to last a lifetime. The circular one was considerably more difficult. The online videos suggest that this material is easily flexible, but to make a circle with two panels (as shown in the videos), I needed two ratchet straps and 3 people. While the panels are flexible, closing the second seam is very difficult because when bringing the two panels together into a cirlce, the edge of the two panels butt in a way so that they do not slide againt one another and prevent closing the seam. I am very experienced in construction and the only way I could get this to work was by strong-arming them closed. Otherwise, I am happy with them. Erin at Henderson was very helpful throughout.

Working out well on my hill although videos alone were not sufficiently clear about attaching posts to ribs. No written instructions I found. Thankfully, Erin at Henderson clarified for me including a better drawing of how to attach. Self tapping screws for post bracing will require a little muscle to screw in since posts have no pre drilled holes. I also had to cut off bottom flange when attaching posts at the ends so the panel and posts would be truly vertical. Used cement at footing as recommended.

Great to deal with

After I placed my order, they called within minutes to discuss what I ordered and caught a mistake I made and fixed it. Got the product the following week. I LOVE it and very easy assembly! I will be buying more from them...awesome company with awesome employees! Thanks!

Ask a Question


Ask a Question
  • Do I really need anchors or bracing? If so, how many do I need? Which style do you recommend?

    Yes, anchors/bracing are important to the long-term stability of the edging.  In almost all cases, 2 per section is recommended. There are 2 choices:  1.  The universal turnbuckle style simply clips to the back of the edging bracket and is extended via a chain diagonally where a peg is pounded into the ground.  2.  The anchor post is screwed to the side of the bracket on the back of the edging and pounded into the ground vertically. The anchor post works well in normal soil conditions.  Concrete should be used around the post.  The universal turnbuckle brace works both in normal and soft ground conditions.  Please note that in soft ground conditions, concrete is recommended around the peg and nails as well. As far as ease of install.  Neither is hard to install, but the Universal turnbuckle style is probably the easier of the 2 methods. Note: When connecting 2 flexible Sections together to form a circle you would not need bracing, anything larger you would.

  • Can the rigid and flexible edging be joined together?

    Yes, they both have the same connectors, so they can be joined together.  In fact, the 9.5”, 15.75”, and 22” can all be connected together at the top.  This helps in situation where there is a slope, and you need to bury a portion of the edging.

  • What type of saw should I use if I need to cut the edging?

    The manufacturers recommend an angle grinder.  The main point in selecting a saw to cut with is that it uses a metal cutting saw blade and that you are comfortable using it.  If you are not comfortable using a saw, we highly recommend getting a professional’s assistance.

  • When do I need to use a joining sleeve?

    Joining sleeves are used to reconnect edging that has been cut.  If you cut the edging, therefore cutting off the pre-built-in connectors, and then need reconnect it to another piece and joining sleeve is used to re-join the pieces.

  • What is included in the price of a single section of edging?

    Included in the price of the edging are 1 – 7-foot section, a joining plate to connect the edging to the next section, and 5 long twisted nails.  Bracing/anchors, premade corners, and joining sleeves are purchased separately.

  • What are the dimensions of the pre-made corners?

    Each arm of the corner is inches.  So, 10 inches then a 90-degree bend and another 10 inches.

  • Is this product suitable to use as a retaining wall?

    Yes, it can be used for retaining, but only up to the height of the edging. For instance you couldn't put it at the bottom of a steep hill and expect it to retain, but you could do stairs on a hill retaining up to 22" at each level.
