ABSTRACT:
An overhead hanger unit for concrete forms, with a first hanger form having a first portion engagable with a first curb form and a second portion extending from the first portion, and a second hanger form having a first portion engagable with a second curb form and a second portion extending from the first portion. A pin may be carried on the second portion of the first hanger form and a slot may be formed in the second portion of the second hanger form, wherein the second portion of the second hanger form may be aligned with the second portion of the first hanger form and the pin engaged with the slot. A coupling device may be engagable with the pin to secure the first hanger form to the second hanger form at a selected position such that a distance from the first curb form to the second curb form may be adjusted by an amount substantially equal to a length of the slot. A pivot connection may be provided between the first portion of the second hanger form and the second portion of the second hanger form, such that the first portion may be rotated at an angle relative to the second portion.
