HANS DeviceQuick Click Helmet Attachment, fitting SA Helmet

Everything bolted right to the helmet and fit fine.

Does not come with the wrench. otherwise they worked as required.

I used it for the first time this weekend. Well made product, and it worked exactly as it should.

Totally complete installation kit, super easy if your helmet is predrilled.

Wrench was not included which is why I paid extra for this kit.

Not the right linkage for my Hans Device- better description needed for which Hans Device.
