Description The first real improvement in rail sign holder design is that it weighs half as much as a steel sign holder. A large handle clamp makes attachment to the rail easy without pinching your fingers. Easy-open holder never rusts. The double roll bar keeps signs from falling off in the wind. Sign plate is NOT included. We have a wide variety of OSHA-mandated sign plates to choose from. View OSHA-Mandated Blue Flag Sign Plates Weight: 6 lbs. IMPORTANT: This sign holder is designed to accept 12”x 15” and 15”x 18” Aldon manufactured sign plates with item numbers starting with “6” or “7”. Other sign plates may require additional mounting holes to be installed by the customer. Aldon can install custom mounting holes upon request for an additional charge.
