This Stainless Steel Angular Flush Rack with Downspouts for Keyhole Suspended Primate Cages is fabricated from dieformed angles and channels. The angle uprights’ lower ends have caster couplers. The angle uprights, angle crossmembers, and channel crossmembers are butted at all joints and welded for strength. Each cage is held securely in place with three keyhole interlocking studs. Under each tier of cages is a stainless steel welded trough pitched towards the downspout. The trough's ends and back are formed-up above the bottoms of the suspended cages. In addition, the trough's front edge is formed-up to create a lip. The rack has a glass beaded satin finish, removing any discoloration. The rack is equipped with chrome plated swivel casters with 5" polyolefin wheels, two with wheel brakes. Swivel and axle bearings have seals and zerk grease fittings.
