Check the listing for details. 14mm 30° 45° 60° Degree Clear Glass Recycler Ash Catcher W/O DOWNSTEM *READ ALL*. Condition: New. Listed at 15.89 USD. You must be 21+ years old to view/buy this item. This item is solely intended for tobacco use only, in respect to local & Federal regulation. The craftmanship is top-shelf on these Recycler Ash Catchers, they just don't sit well in most bongs, angle-wise. The glass is thick and the seams are solid.The elbow angle° is peculiar. Technically, these can't be called 45° because they're off from true 45°; hence '30° 45° 60°' in the title of this listing. I don't know if you'd call these 30° or 60° and the Ash Catcher market isn't fine-tuned to anything other than 45/90. Maybe that's how these ended up being manufactured this way...If your bong is a Beaker, these may be manageable. If your bong is a Straight Tube, chances are the bowl-side of the downstem angles up more than true 45°. If you have a Straight Tube (or any pipe) and the bowl-side of the downstem angles up more than 45°, I recommend you continue your search for ash catchers...else, enjoy the fruits of this off-batch. THIS LISTING DOES NOT INCLUDE A DOWNSTEM. THESE WILL REQUIRE A 3.0" 19/14mm DOWNSTEM FOR OPTIMUM PERFORMANCE. This is a link to the Same Recycler Ash Catcher w/ Downstem I'm trying to liquidate this batch of strange Ash Catchers, so returns will not be accepted.Because no returns are accepted, please ask any/all questions, prior to buying.
