Want to fit a sign to railings, gate or wire fencing?
Order a sign with backrails then order the Gripper bar set you need below. A gripper bar set includes 2 gripper bars, 4 Square Head Bolts, Nuts and Washers- See how to use below
Choose Gripper bar widthÂ
Choose a gripper bar width less than the width of your sign & wide enough to trap several down bars.
Choose a Bolt length
Measure the rail, gate or fence thickness ie 50mm then add 50mm so that the bolt protrudes enough to attach the nut & washer.
