The 1000*800*840mm cage is also called the A-5. A standard A-5 has 50*50 mesh, 5.6mm wire diameter, a bottom 5+2 channel-steel structure, and a 1-ton load. But for the same outer size, Xintongnuo also builds other variants for different load needs: C-5: 1000*800*840mm, mesh 50*50, wire diameter 5.0mm; B-5: 1000*800*840mm, mesh 50*50, wire diameter 6.4mm. Beyond these wire-based models, this size can be rebuilt into various non-standard cages: square-tube cages, caster cages, hollow-panel cages, towed cages, and more. If your material is light, C-5 saves cost; if it is heavy, B-5 is steadier. Unsure which fits? Send Xintongnuo's sales staff the material weight and use case, and we will spec it for you.
