Stainless Steel Blank Tips are to be used in place of a regular nozzle tip where you do not currently want the overhead system to spray. The blank tip has no hole for the insecticide to spray from. For example, if you are temporarily converting a stall to storage, you would put in a blank to plug the nozzle, allowing you to later replace it with a functioning tip when you convert it back to a stall.
Shoo-Fly is affordable, and saves us money. I would give them 5 out of 5 stars. Truly a well-organized, well-thought-out product that each and every horse owner could be well served by.
