Roll 'n' Pole Portable Sign Holder 

• Rolling Portable Pole Sign Holders are made from rustproof plastic technopolymers to withstand harsh environments. Whether its snow, rain, sleet, or the baking heat of summer this durable material won't fracture, break or degrade.

• The heavy-duty base and split flanged bushing provides support to the sign post - helping to maintain stability when subjected to wind loads of up to 40 mph.

• Pre-drilled poles are made of High-Density Polyethyene (HDPE) which is thicker than PVC and won't get brittle in low temperatures - delivering higher impact resistance.

• For additional weight and stability in windy conditions, the base of the sign holder has two built-in ballast ports that are able to accept water, sand, or gravel. The ballast port has a capacity of 2.5 gallons, adding an extra 19-21 lbs of weight.

• Includes four new and improved soft edge 'Stability Plates' with rounded corners allowing your sign to sit flush against the pole to prevent twisting and bending in the wind. Sign holders are compatible with 9" x 12" to 24" x 24" and 12" x 36" sized signs.

• Alcoved wheels are suspended above the ground and can be deployed by simply tipping the base using the ‘EZ-GRIP’ finial knob located on top of the pole – providing easy transport or maneuverability.

• The base is available in 4 colors: standard black, danger red, handicapped blue and safety yellow.

• The post is available in 2 sizes: a standard 46" in length and a deluxe 58" in length.
