CleanSpace Helmet attachment hook

With the strap hook, you can secure the CleanSpace engine unit (all 3 models) to your safety helmet, so you can get relief from the weight of the engine unit. The strap hook is designed to securely attach the engine unit, so you can wear it without worrying about it slipping off or falling down. The strap hook is especially useful if you need to wear the engine unit for a longer time and want to avoid tired shoulders or neck from the weight.
