Create a world-class tennis court with the Grand Slam 3-Inch Round Competition Tennis Posts from Gared. While the proper surface, netting, and fencing around the venue are important aspects of the tennis court, the net post may be the most crucial of them all as they help keep the net firm for optimal play. A strong post is required since it will be subject to the constant pull of the net. To handle this, the outside diameter of these posts is three inches to provide a sturdy foundation. The aesthetically pleasing unit features an internal brass winder and your choice of square or round posts. An internal brass winder keeps parts away from direct contact with the environment for added durability, making it perfect for areas with harsher climates. There are no functional differences between a round and square post. It is up to personal preference, however, it is important to know the shape for the addition of post sleeves to ensure a proper fit. A powder-coated finish in your choice of green or black adds to the durability by keeping it looking brand new for years to come. Net and ground sleeves sold separately.
