These Proper Brolly Clamps will fit all leg systems round, square or octagonal up to 21mm & can be fitted to platform or seatbox legs.
This unit will accept all brolly spikes currently on the market today.
The double corner clamp screws ensure that your brolly pole is gripped firmly in place with no chance of coming loose & because your brolly pole is gripped in this way it also ensures that there is no chance of your brolly pole snapping off in strong winds unlike other brolly clamps available with a single centrally positioned screw fitting. This brolly clamp can also be used for other adaptations.
Zinc plated finish.
