Monoflo BC4844 Collapsible Bulk Containers

Monoflo 48x45 Collapsible Bulk Container 

The Monoflo BC4844 series is a collapsible bulk container with a 48 x 44.5 in. footprint in four heights: 25, 33.8, 41.8 and 49.8 in. outside. Monoflo builds it from high pressure injection molded plastic with all-plastic latches and a two-piece welded base with an I-beam design. Monoflo states that the I-beam cross section increases base strength by up to 40%, but it does not publish the baseline for that comparison.

The two shorter heights collapse to 12.5 in. The 41.8 and 49.8 in. heights use a collar system and collapse to 20.5 and 28.5 in., so they return fewer containers per truck. Monoflo lists 252 collapsed containers per trailer for the 25 and 33.8 in. heights, against 140 for 41.8 in. and 84 for 49.8 in.

Monoflo’s sheets do not list a load rating or a stacking rating for this series. Check both ratings for your height before you order, and fill only to the fill line so the container above seats properly.

Selecting the Right Model
◆ Choose 25 or 33.8 in. when rack or trailer clearance limits stack height and when return freight matters. Choose 41.8 or 49.8 in. when you need more volume from the same footprint.
◆ Allow for the collar system on the two taller heights. They collapse to 20.5 and 28.5 in., so closed-loop savings are smaller than on the shorter heights.
◆ Load to the fill line (18.2, 27, 35 or 43 in.), not to the top of the wall.
◆ Add the container weight (99 to 155 lb) to the load when you check forklift and rack capacity.
◆ Confirm the load rating and the stacking rating for your height.
◆ For tighter aisles and smaller loads, Monoflo also makes the BC3230 on a 32 x 30 in. footprint.
