The importance of keeping your flue Space clear
What is Flue Space? A Flue Space is vertical lines of sight from the floor up to the ceiling within a pallet rack system. There are two types of flue space; transverse flue space and longitudinal flue space. Transverse flues are the spaces between rows of storage in the direction of loading.
Longitudinal flues are the spaces between rows of storage perpendicular to the direction of loading with a width up to 24 in. (600 mm). Longitudinal flues greater than 24 in. (600 mm) wide are treated as aisles.
