### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Lightweight, but sturdy and height adjustable
  

*by C***N on Reviewed in the United Kingdom on 21 June 2024*

We are in the process of building a decking on uneven ground and after viewing many useful vlogs on you tube detailing the initial decking framework decided we didn’t really want to use wooden posts (treated) and secured with postcrete as many of the vlogs were recommending in addition the need to possibly replace the rotting posts in several years time being a factor, however we came across these plastic adjustable decking feet, so thought well these aren’t going to rot, you obviously still need to put a concrete base underneath each foot but with the advantage of being adjustable thought worth giving them a try. The feet are lightweight but sturdy, very easy to fit and as stated the bonus of being adjustable were perfect for our decking project thus far we have not been disappointed and would highly recommend

    Ideal for stabilising a suspended floor
  

*by F***M on Reviewed in the United Kingdom on 27 May 2023*

Too much spring in a suspended floor was cured by removing the boards, in my case chipboard.  I then placed a piece of 3 x 2 across the floor joists which in turn was seated on adjustable risers at intervals of approx 50cm . The risers adjust to tighten the cross joist under the floor joists.  Although tight to the sub floor and the underside of the cross joist they are held in place with a screw through a small flange on each riser.  Note that they are available in different heights with a good 50/60 ml of adjustment to each one. Its worthwhile putting a  decent packing of ply between the sub floor and the base of the riser for extra stability.  A really useful product which I have now used on the whole of the ground floor of the house, insulating between the joists with kingspan.

    Great Time Savers
  

*by C***  on Reviewed in the United Kingdom on 12 June 2023*

I only bought a few of these to help sort levels before installing cemented posts. I found these very useful for adjusting heights and moving between areas. Handy too, where the joist is slightly bevelled. Only criticism is the green part is slightly brittle and bits snap off easily if you catch it with your boot.
