I understand there are threads that have everyone's accessory parts and all, but this revolves around a question of mine at least. I purchased the Triple perc bong from Grasscity on Monday, and ever since then I've been looking for a nice addon for it like a pre-cooler and/or ashcatcher. The joint size is listed as 18.8 > 14.5, I know the sizes but what does the ">" mean? Is it that the size gets tighter the further down it goes? I also want to open this up to people who want to talk about their specific accessories, maybe point me in a better direction, or just show off how intricate your technological bong really is.
