Rain Bird Maxi-Paw Wrench — Model 42064, Pop-Up Sprinkler Tool

The Rain Bird Maxi-Paw Wrench (model 42064) is a purpose-built maintenance tool for Rain Bird pop-up impact sprinklers. Designed to lift the cover and remove the internal assembly without excavation, it speeds routine service and helps keep systems operating at peak performance. Technicians and DIY landscapers rely on this simple, single-piece wrench to reduce repair time and minimize turf disruption during routine maintenance.

• Compatible with Mini-Paw and Maxi-Paw pop-up impact sprinklers, including LG-3, AG-5 and 2045A models—the wrench provides a precise fit for common internal assemblies.
• Chrome-finished construction offers corrosion resistance and long service life in wet conditions; the durable finish helps the tool resist rust on service carts and in outdoor environments.
• Flat-tipped handle lifts the sprinkler cap gently without damaging the cover; the extended hex shaft unscrews and lifts the internal mechanism so screens, springs, and nozzles can be inspected or replaced.
• Eliminates the need to dig up sprinkler heads — perform nozzle changes, spring placement checks, and cleaning at grade to restore uniform watering and reduce overspray.
• Compact, single-piece design fits easily in toolboxes and service carts; simple, intuitive operation makes it suitable for contractors and homeowners alike.

To use: insert the flat tip under the cap to pry it up, then seat the hex portion over the internal mechanism and turn to unscrew. After servicing, reverse the steps to reinstall the mechanism and cap. Keep the wrench clean and dry after use to extend service life. The Maxi-Paw Wrench (42064) is an efficient, low-cost accessory that helps maintain reliable irrigation performance across lawns, sports fields, and commercial landscapes.
