19mm Dropdown with Reclaimer:
The benefit of having a drop down adapter is that it allows you to move your nail further from your rig, reducing the likelihood of stress fractures and cracks in your glass from rapid temperature change.
Reclaimers help conserve concentrates by catching them as they drip down the downstem. Rather than washing out your rig when it gets clogged, use a reclaim catcher to catch and reuse your excess concentrates. This not only saves your wax and keeps your glass nice and clean, but also works similar to a drop down, pushing your hot nail away from the joint and prolonging its life.
