The 33L Large flag water base is the heaviest and most durable water or sand fillable base option within our flag range. It's recommended for use with our large and extra large teardrop and feather flags but can be used with smaller sizes for additional stability in windier outdoor conditions.
Hollow, Fillable Flag Support Base
The base is hollow and can be filled with up to 33 litres of sand or water to provide maximum stability and performance. This is substantial enough to support all sizes of portable flags in our range outdoors including large and extra large sizes.
Extra Support In Higher Wind Speeds
Large 33L Flag bases can withstand wind speeds between 13MPH and 18MPH (Beaufort Scale 4) when used with our largest feather or teardrop flags.
For use with smaller flags, this heavy duty support base provides maximum weighting for use in even stronger winds.
Water Or Sand Weightable
The 33L flag base features a stopper on the top allowing it to be filled with water or sand for ballast. Water provides 33L of weighting whereas filling with sand provides 50KG of weighting.
When using this support base in very cold or sub zero temperatures, we recommend using sand for weighting in order to prevent freezing and expansion of the water that could cause damage.
Adjustable Grip Collar
The large water base has an adjustable screw down collar so it can tighten and clamp onto most types of feather and teardrop flag poles of varying diameter.
Built In Carry Handles
The moulded base features two carry handles in order so it can be picked up and carried with the minimum of effort.
