Abstract

A roll up door for trucks and the like comprises a one piece plastic sheet member which encloses the door opening. A plurality of stiffening panels are attached to the sheet member in spaced relation and preferably bonded to the sheet member. Rollers and attached axles are mounted on the panels via bores which receive the axles. The rollers ride in roll up door tracks which capture the rollers and door to the tracks in conventional fashion. The sheet member forms living hinges in the spaces between adjacent panels.
