Eurolite TH-25 C-Hook 25 mm Silver

I needed a relatively large number of small clamps, to fit onto 25mm steel box section. These were perfect as they're not too expensive, and are just the right size to fit. The small metal plate that prevents the bolt from damaging the truss is attached by a small screw, and on several of mine these have come undone over time, meaning the plates have fallen off. Other than that, they're great.
