(6 Pack) Chrome Sprinkler Guard Fire Sprinkler Head Cage for 1/2" NPT Recessed and Sidewall Sprinkler Head

Cheaply made. One had a broken weld making it useless. I paid $39.99 for 6 and I only needed two planning on giving some to my neighbors. Having some familiarity with Asian manufacturing, I would guess all-in, shipping included to the USA, this item's actual cost is 50 cents or less per piece. It stays in place if positioned just righ, but if something hits it even somewhat hard it is falling off. I would not buy again, but need something to make the head a bit bump proof and more visable in a garage. Installing SafeRacks overhead shelving in the garage and need to be able to create some space around two sprinkler heads.
