I am looking for some *off set* hooks to hang several bikes from the central beam of my metal shed/garage. At *unnings, all the hooks seem to be straight, whereas I want to hang the bikes at 90 deg to the supporting beam, which is 145mm wide. I have tried to bend a planter hook, but the effect is not quite right. I would like to have the hooks free hanging, rather than fixed to the walls if possible. Any clues ?
