  • The Little Things Matter

    These have made me so happy and I'm sure every builder out there will feel the same... It's the little things in life!

  • Saves On Labour Costs

    These props are great, what they cost over and above a normal acro you will gain back in labour costs easily as they become a one man operation.

  • Easy To Use

    I can't emphasise enough how easy it is to use compared to the standard acrow prop. Saves so much time as well. I can 100% recommend these to anyone thinking of purchasing some.

  • Oli Wildsmith

    You'll never want to touch an acrow again after using these. We've replaced all our props with J-struts, they're brilliant - much quicker and no more pinched fingers!
