Can anyone tell me where we can buy sand collars for rain bird system heads. Approx. 4 inch dia. tube with an 8 inch flat flange to keep sand or dirt from entering the head and also prevents grass growth around edge or the head.
We have a condo complex with about 300 heads to keep working. We bought the tools that cut the grass from around the heads but can a sand collar be used on turf to stop grasses from covering over the heads? Never seen them used in Ohio. We have a Rain Bird system that works well( except for people driving off the driveways and running over the heads.) Wondered if anyone has used the collars with success and where can they be purchased from and what is the cost?
