Those particular ones are the screeders from whom I borrowed the pump. He has them made by his brother in law I think. Dave parish of screed floor limited. You can contact him through his website if you want some. Screed Floor | Concrete Floor Contractors
Shame about the D/socket hitting into the molding.. and i would heat the floor to allow the wood to expand before you paint it.. or you will get annoyed when dark lines appear as the mdf expands lol lol ..
Yeah I was annoyed about the socket too.....hadn't got enough tail on the able to move it any further across...... Never mind. They won't be seen that much. Good idea about the floor..... Hadn't thought about its effect on the MDF. Ta.
