Evaluation of Rollup Sign HolderAbstract:
The rollup sign holder is a product of Lang Products International, Inc. The rollup sign holder consists primarily of an L-shaped hollow steel tube with a 2-inch square cross-section. The rollup sign holder serves a need for a warning sign close to a vehicle during moving operations. There is a perception that such signs improve safety. This evaluation recommends that the rollup sign holder affords an additional margin of safety beyond the stationary signs required for moving operations and should be adopted wherever practical.
