Postfix Trellis Fence Height Extension Arms VALUE PACK of 5 PAIRS - NO TRELLIS INCLUDED!

Excellent post extenders and do the job perfectly. Easy to attach to trellis with small screws and there are plenty of holes through which to screw… although you won’t need all of them. Fit perfectly in the channels of the concrete fence posts. Depending upon how tight your posts are to the fence panel you might need a plank of wood to push open the gap to allow these to be inserted but that’s not a fault of the item. Holds the trellis in very sturdy. My cats walk across the top of these with ease as they don’t move, however trellis on my neighbours fence which doesn’t have these wobbles a lot

Item was perfect for what we needed (to add height to existing fence panels at pretty low cost). Only weird thing is that the actual extenders themselves were seemingly all identical, meaning the screw holes were in different places because you basically just flipped it depending on if you were putting it on the left or right of the fence post. Definitely not a major thing, but just means the holes were in different places for left vs right. You'll need a mallet (not a hammer) to get them in place - and a previous reviewer had a great tip to use gloves as they are pretty sharp on the edges. Delivery was pretty quick as well. Would recommend this for people wanting to extend the height of fences without wanting to spend a load of money.

We bought these for the tops of our new fence. I asked the fencers to drop the fence panels during fitting by a couple of inches compared to the tops of the posts, which would make the trellis sturdier, but there's no requirement for this - your panels can be level with the concrete posts and it will still work. The metal supports, which are 50cm long, slide down between the panel and the concrete posts by 20cm, if your trellis is 30cm (1ft). 20cm of metal support is hidden between the panel and the post. This is why it's so strong. If you have 45cm trellis (foot and a half), you'll only have 5cm of metal support below the trellis, and between the panel and the post, so less strength, however, you don't necessarily need the metal to be level with the top of the trellis, and could drop it down to ensure it's secure. The metal is notched with feint centimetre marks so you can see how far it's gone down. We fitted the supports to the concrete posts first, then offered up the trellis into the gap, rather than screwing the supports to the trellis first. Cons, which are not the product's fault: 1. Your concrete posts are unlikely to be a perfect fit for these metal supports, and may take your brute strength to bang them in. Use a lump hammer and a piece of wood over the end of the metal or you'll damage them. We had to use a grinder on one of the posts due to excessive concrete in the groove. 2. The dimensions of trellis are usually 180cm x 30cm. You'll usually find fence panels are 6ft or 183cm. This means your fence panel is marginally bigger than the trellis by a 3cm difference. Before you buy your trellis MEASURE it if you think you're getting 183cm. They're often listed online as 183, but when you get them, they're 180. You'll need to pack out the 1.5cm gap at either end between the trellis and the metal support. This made the whole operation more arduous than it needed to be, although was resolved by a visit to our local fence merchant from whom we got slithers of timber precisely cut to 1.5cm for this very purpose! As long as you're good with a saw you'll get a neat edge and you won't even notice it's been packed out. You then screw through the pre-made holes in the metal, through the slither of wood and into the trellis to secure it all. 3. The gap between each trellis is unavoidable, but presumably, if you're buying this you're aware and are OK with it. Overall: VERY PLEASED!

Have added to trellis panels on top of fence and on concrete posts so hopefully works. Easy to install and have yet to check if they are going to last or stop trellis rocking. Holes could be slightly bigger for screws fixing. Bit shiny against wood fencing so may have to paint them.

Brilliant for extended fencing. Have used to put trellis on original fence. Just slide in and a couple of screws in pre drilled holes secure it well. Has survived strong winds and neighbours have commented on how nice the fencing looks.
