This is a permanent lid replacement for Littermaid receptacle lids. Unlike the factory Littermaid receptacle covers, this LID is durable, easy to install, and easy to remove for cleaning.
The LitterWorks brand has 3 unique features: 1) An extra fastening nut which keeps the lid from bending/warping during install.
2) Adjustment slots in the lid for fine tuning the fit depending on your model of Littermaid.
3) Compatible with both Littermaid receptacles AND the LitterWorks litter disposal system chute.
