Provide air flow while maintaining solid security. Fresh Air terrarium covers are designed especially for the unique needs of reptile environments. Screening promotes the healthy exchange of air needed to keep cold-blooded reptiles healthy and active, with a metal mesh tough enough to withstand the clawing of the largest pets. Designed with lighting hoods in mind, the mesh also stands up to the high temperatures heating bulbs generate. Long lasting black steel frame keeps its shape through years of daily use. For added security, accessorize a Screen Cover with screen clips, combination locks and a cord access port [sold separately]. This Product/Package Measures: 1.60 in. L x12.90 in W x37.00 in D
