The new range of Holman metal sprinkler spikes are an excellent choice when looking for a strong, reliable metal irrigation system. This spike is best suited for use in garden beds, areas where a hose is used to reach remote watering (eg: under a tree) or can be pushed directly into lawns areas. Featuring a quick release 12mm snap on male connection, this spike design is able to be set up in minutes. The spikes are supplied "without" spray heads so you are able to attach the style that best suits your watering requirements. Watering options: The 1/2" outlet offers a variety of different sprinklers to be connected. Commonly, an impact sprinkler is attached & the spike pushed into a lawn. The spike can also be re-located if watering a large lawn area. Pop up sprinklers are also a good option! It's very common for a sprinkler to have a female 1/2" thread and they can screw directly onto the spike. These also offer a neat solution with the nozzle protected inside the sprinkler cannister. Pop ups have a range of fixed or adjustable nozzles so any spray pattern can be found. Using a pop up on a spike, gives you the flexibility of locating this sprinkler where it's needed & can then be easily moved when the plants grow. A lot easier than moving a rigid sub-surface plumbed system. The last option is attaching a poly riser with a spray head. This provides a "tall" sprinkler option and suits most garden bed applications. the height allows the spray to reach "over" the plants to fully water the surrounding area or garden bed. For any of these sprinkler installations onto the Holman metal spike. Simply screw directly onto the ½ BSP male thread and clamp down on the rubber washer to seal. Each Holman metal spike features a strong 4 sided rib, which allows installation into hard, dry or harsh soil conditions a lot easier. All along keeping the sprinkler standing firm and steady.
