A: There are longer versions of this product available which are 800mm long. These would allow you to extend using a 2 foot trellis.

A: Just wood screws not too long

**Q: The pic she show two different shapes diamond or square. What shape are the holes.**
A: You only get the metal brackets. Not the trellis itself.

**Q: Is this suitable for a 450mm (1.5 foot) high trellis panel, or would the 795mm version work better?**
A: These are suitable for 300mm high trellis as they are only 500mm long, giving 200mm engagement with the concrete fence posts. You will need the longer version for your 450mm panels.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    SUPERB, AND WELL MADE
  

*by B***R on Reviewed in the United Kingdom on 24 April 2015*

these extension arms are great if your fence panels are right at the top of the posts as mine are and would be just as effective if they were not. very easy to fix to trellis and to fence panel with the pre-drilled holes which allows plenty adjustment for different trellis heights. I purchased 8 pairs of these superb arms to do the full length of my garden and now I won't worry when the wind starts to howl because I know the trellis will be held fast with the 10 screws holding each trellis in place.HIGHLY RECOMMENDED

    Does the job
  

*by R***6 on Reviewed in the United Kingdom on 24 August 2021*

    Good idea, useful product
  

*by G***L on Reviewed in the United Kingdom on 25 August 2015*

Look good and strong enough to do the job, fit is very good to my posts and panels. Could be another 100mm longer for more engagement with the post and thicker steel, but for extending the fence with 1 foot trellis no problem.Would certainly buy again. Arrived well packed.Just received 3 more pairs and did a good job again. Quick and easy to fit with 1 foot trellis and feels strong. Would recommend buying strong good quality trellis to strengthen the finished job.
