A reclaim catcher is a smoking accessory used with dab rigs and bongs. It collects excess concentrates or resin. This helps users save material that would otherwise be lost. It also keeps your rig clean and efficient. Dab reclaim is the leftover concentrate that collects inside dab rigs. It forms after vaporizing cannabis concentrates. This sticky residue clings to glass surfaces and reaccumulates over time. Surprisingly, reclaim still contains active compounds like THC.
