I’m looking for suggestions on floor fixings to hold sheep hurdles/race joiners to the shed floor. I’m looking for alternatives to just a rawl bolts/thunderbolts as I want to beable to take the handling system to bits and clean out with the loader or use the shed for other uses at different times of year so they need to fit flush with the floor. Do I bite the bullet and just concrete in 50mm sockets? Has anyone done anything different?
