Tier Drop Sorters are the only literature organizers that let you keep adding on — one tier at a time! Individual tiers stack together to form any size unit you need. You can create a stack up to 24 tiers high — that’s a total of 72 slots! Need more slots? Add another stack side-by-side.
Tier Drop Organizers are a strong, economical, and versatile way to sort and store all of your literature forms and mail. Tier Drop’s unique “ripple wall” design gives it strength comparable to steel, but costs 25% less! Constructed from durable injection-molded polystyrene.

Tier Drop has a LIFETIME GUARANTEE!
