PS10+ posi strut spec and weight (1 answers) Hi . I need to buy around 600 posi struts for the posi web floor joists. Please confirm the span of the PS10+ and are they suitable for 212mm residential posi joists? Are these struts interchangeable and can be fixed on the left and on the right hand side of the floor joists? What's the actual height of these 160mm or 212? I need around 600 of these struts how much they weigh and how many in each box as I have only a small van?
