450mm corner post. Its galvanised and does the job. If you are going to do a timber sleeper retaining wall then these will sort you out and help you get it done. It will make the job look professional.

This was a great product. Just needed a string line and a level and some quick set cement

Super easy to use along with with a string line and level, however the price really adds up and product is no better than generic varieties. Recommend shopping around.

I used this product to put in over 30 sleepers, two sleeper high retaining wall and a 17 sleeper raised garden bed, very easy to use

Can't recommend these highly enough. Extremely easy to install, if I can do it anyone can.

I love the results, although when we where done somebody said if you bend them a bit u can actually fit tin 70mm sleepers. I would have preferred that as that would be a better fit. Now they have space

Poor quality

They are not galvanised correctly. I think they are of poor quality but have now where else to get them from.

Retain It sleeper channel
14 September 2022

Not a bad little product, shame they're not Australian made though.One thing that's crucial is that no matter what sleeper you use, whether it's the rather ordinary needle treated heart timber stuff from here or better quality pressure treated from elsewhere, all the sleepers should be cut in half and keep to 1200mm centres where ever possible to avoid bending and bowing like bananas over time as the timber dries and shrinks and wants to move around. If you go up to 75mm or 100mm thick sleepers, you can push it out to 1500mm centres but the shorter the better long term.Good easy product to use, not overly cheap though. I have found some good alternatives out there that look somewhat stronger and are actually a little cheaper too ... not everything is cheapest at ... MoreNot a bad little product, shame they're not Australian made though.One thing that's crucial is that no matter what sleeper you use, whether it's the rather ordinary needle treated heart timber stuff from here or better quality pressure treated from elsewhere, all the sleepers should be cut in half and keep to 1200mm centres where ever possible to avoid bending and bowing like bananas over time as the timber dries and shrinks and wants to move around.
