Welcome to PVC Cages                                                 |     home                                                    6 qt rack Arboreal rack Comes in color Black or White 10 Tub Rack 15 Tub Rack 18 tub rack 21 Tub Rack Assembled Comes complete with  tubs and  11" flexwatt as pictured below. You do need a Temp controller to controll the heat Inside measurements of the tubs are 12 d  x  6 5/8 w  x  4 1/4 t Floor space is exactly the same in The Terrestrial and Arboreal Racks. The difference between the Terrestrial rack and Arboreal racks is, Terrestrial rack tubs have feet under the tub and they have a flat inside bottom,  where the arboreal tub has lips on the inside to hold perches and the bottom has a small dip ( round ) along the outside (inside) edge.  If you look at my pictures  you should be able to tell this, both have close up shots of the tub. When considering my racks over other competitors, my racks are made with 3/8 thick material, not 1/4" Also my racks have dual heat, not one single row of heat. 10 Tub has a single Row of flexwatt, the rest have 2 Rows of Back heat No acrylic dowel Anymore unless your racks have them, ( you will need to tell me ) This is the tubs used. The whole back is covered with flexwatt. Two rows of 11" flexwatt ( 4' total)  (2 cords )  ( 15 tub only, 10 tub will have single row. )
