The RECKITT 83721 is an automatic toilet bowl cleaner tablet system designed for continuous in-tank bowl maintenance. Each tab mounts via a flexible hang-up hook that fits standard bowl rims and dissolves over approximately four weeks, releasing cleaning agents and fresh scent with every flush. The antibacterial protection is molded directly into the hang-up hook itself, which resists odor-causing bacteria between tab replacements. This 2-pack provides up to eight weeks of continuous bowl cleaning without repeated manual scrubbing. Facilities maintenance staff and janitorial professionals commonly deploy these in commercial and residential restroom settings where consistent bowl hygiene between scheduled cleanings is required.
The 83721 is suited for standard residential and light-commercial toilet bowls. The flexible hook adjusts to fit varying rim profiles. For best results, the tab should be positioned toward the back of the bowl to the right of center, away from the direct path of the bowl refill water but still in contact with it to activate cleaning agents on each flush. The 2-pack format reduces restocking frequency in multi-fixture facilities.
Designed for use with standard residential and light-commercial toilet bowls with a hang-over rim. The flexible hook is intended to fit most bowl rim configurations.
Installation requires no tools. Hang the tab assembly over the interior bowl rim toward the back and to the right of center, keeping it out of the direct stream of the refill water while maintaining contact with bowl water flow. Replace the tab every four weeks or when fully dissolved. No plumbing shutoff is required for routine tab replacement.
