Hey building managers and safety-conscious folks! These DOITOOL fire sprinkler covers are exactly what you need to protect your exposed sprinkler heads from accidental bumps and knocks. Made from sturdy iron material that won't deform easily, these guards create a protective cage around your sprinklers while still allowing them to function properly in case of emergency. The 8x6x6cm size fits most standard sprinklers and they work with upright, pendant, or horizontal sidewall positions. Perfect for offices, schools, hotels, restaurants, warehouses - basically any commercial building where people might accidentally hit sprinkler heads. Installation is super simple and they're built to last through years of use. Just remember - these are for exposed sprinklers only, not the recessed ones with escutcheon rings. At 2 pieces per pack, you can protect multiple sprinklers throughout your facility. Much cheaper than dealing with accidental sprinkler discharges that can cause thousands in water damage!
