Dragon Ledges are offered as a retro-fit kit so they may be installed on screen cages you already own. Sizes are available to fit screen cages from Dragon Strand, ZooMed ReptiBreeze, LLL Reptile, and DIY Cages.
The medium size cages have four Dragon Ledges per package and the largest cage sizes have five per package. A five pack allows a more effective coverage of branching within the larger space. Please see the Dragon Ledges Selection page to select the right size kit for your particular cage.
