Sieve Storage Racks are constructed of stainless steel and used to organize test sieves for quick access when setting up tests, and prevent damage to the sensitive mesh. Compartment bottoms are neoprene-lined and inclined to keep sieves in place. Holes are built-in for mounting on 16in (406mm) centers and for bolting racks together vertically and/or horizontally. Non-skid rubber feet are included to allow for stable countertop use. The bottom front flange has a 1.25in (32mm) high area to label slots for sieve sizes. Shipped unassembled.
