We have been supplying commercial quality irrigation products on eBay since 2008. There is a reason why until now that we have not sold any impact sprinkler spikes on eBay, we have on a couple of occasions given them away free with a purchase of a certain impact sprinkler. The reason being is all the (aluminum/pot metal) sprinkler spikes being manufactured are basically junk and are pretty much guaranteed to bend or break in a season or less. Nothing a company that relies and depends on repeat customers and referrals would ever sell. 

 Introducing the Pro-Spike by Lawn Anchor which has every feature you could ask for in a sprinkler spike. Unsurpassed durability and a 10 year warranty on the spike. Last season we had lots of requests from customers who wanted a way to water different size areas with the same sprinkler, that was simple and couple be adjusted by simply turning the faucet. Then I opened a box of all brass Rain Bird 1970's era full circle spray heads we had at our shop and I thought these would be perfect, and they are! These bullet proof heavy duty spray heads once installed by the millions before cheap plastic took over when installed on a sprinkler spike once again become a awesome watering option for lawns, gardens, planters and more. Now with a turn of your faucet you can water various size areas up to a 15 foot diameter and with no moving parts on our Prospike its going to last you for years

You won't find anything close to this quality or performance anywhere but Sprinkler Innovations/Hose End Sprinklers. Comes with a PVC extension to add throw and provide easy installation into the ground.

I guarantee you will love this combo or I will pay to ship it back

The Lawn Anchor Hammer spike is strong enough to drive like a nail into your rock hard soil, with a hammer. The design allows you to apply great force directly to the spike without damaging your sprinkler head. The 2 inch head allows a size-able target for the hammer's impact and also gives you plenty of room for your hand or foot if your soil is not rock hard. The design has been field tested by the inventor for over 15 years. The Offset Design transfers all vibration off to the side of the spike which gives unmatched stability to the sprinkler head "no flopping around". The "offset web" from the spike to the sprinkler gives a non-rotating aspect to the sprinkler when it is engaged in the ground which also adds to the stability of the unit. The finger hole in the web allows a place to apply upward leverage when you want to remove the spike, it also is a place that when storing the unit will turn upside down so the sprinkler head will drain "especially important for gear driven units". It has No Moving Parts no "ring and collar" to break, it Will Not Bend; the Flexural Strength is 40,000 psi. the spike has a Tensile Strength of 27,000 psi. The Lawn Anchor Offset Spike has a 3/8 inch solid core through the center of the spike and the entire unit is reinforced with fiberglass fibers 1/4 inch long in the entire unit and it is "Made in USA." The Pressure test was done with a 20 ton hydraulic press with a 2 X 6 yellow pine with no per-drilled hole.
