Square tennis aluminium posts fixed

The pair of square aluminium sealable tennis poles will be ideal for all your courts whether indoor or outdoor. These poles have the advantage of having their winch system integrated into the pole, this makes it possible in particular to make these poles more secure and the players will no longer be able to bump into the winch when they pass between the pole and the referee's chair, for example. A block is also placed on the top of the post to protect the mechanism from the weather, which makes the latter more resistant over time. This cap is attached by a chain inside the post so as not to lose it.
