14mm opening in a 22mm top cap, stainless SUPER wide bore with heat sinks. Made for/fits Doge v1.
Replaces top cap and driptip of popular RDA's on the market (Tobh, Vulcan, Crest, Asmodella, CIA Halo Cap, Doge). Wide opening compliments large airholes of drippers, eliminating hot juice in the mouth. Big unimpeded draws for cloudchasers.
