The B&B Bundle Cart is a collapsible construction cart like the B&B Pipe Cart, but is designed for the storage, transport, and support of whatever needs to be moved. The fold down brackets of the collapsible construction cart can rest in a lowered position allowing storage, stacking and transport efficiency. Robust 2in square heavy gauge tubing and oversized 6″ caster make the B&B Bundle Cart a great addition to many job-sites across multiple trades. Two versions of Hanger Carts are available.

The modular design makes it possible to add floor option to PN 2036-4E easily. Proudly manufactured in the USA. Patented Gravity Lock System. Secures uprights in position.
