DuraLatch® Crossbracing is constructed of 1.25" wide fiberglass and has three plastic end caps. It is used for MDI’s diamond-shape, rectangular and square DuraLatch® Roll-Up Signs. There are three styles available for diamond-shaped signs– no flag, 2-flag with two integrated flags, and 3-flag with three integrated flags. There are two styles available for rectangular and square signs – without flag bracket and with 3-flag bracket for wooden dowel flags (flags sold separately). The EPDM rubber straps on each DuraLatch® Roll-Up Sign have military-style Lift-The-Dot fasteners in zinc-plated steel. Fasteners snap onto heavy-duty, solid-tip steel posts in the crossbracing.
