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.
Dragon Ledges come four to a pack except the 23″ and 24″ sizes which come five to a pack to allow more effective coverage of branching within the larger cage spaces. Please see the Dragon Ledges Selection page to select the right size kit for your particular cage.
