Anyone know where these can be gotten or fabricated for a reasonable price in the UK? Normally on formwork jobs you have a welder tack a heavy bolt to a steel rod and cut some sleeve from a fence rib or such but I haven't been on a site with welders on it for years now and could use a new one.. Example of the tool in question in this clip
