How it works 1. Spread the cage just enough to clear the sprinkler frame and deflector, taking care not to damage the sprinkler. 2. Release the two hooks on both sides of the shield. 3. Clamp the open end of the cage at the bottom of the sprinkler between the frame and the thread. 4. The installation can be completed without tools and can be installed in the overhanging position. Key benefits Tool installation saves time and simplifies retrofits. Suitable for overhanging or ceiling mounted installations, enabling work in tight spaces. Provides clearances around the sprinkler frame and deflector to prevent damage during installation or maintenance. The cage clamps securely between the frame and the threaded bottom for stable positioning. Hooks on the shield sides allow quick release for removal or adjustment. Compatibility and attributes Function: provides a protective cage that clears the sprinkler frame and deflector while attaching between the frame and the thread. Compatibility: designed to work with sprinkler heads that require clearance around the frame, deflector, and threaded bottom. Performance: tool installation and overhanging position capability for efficient setup. Use scenarios Ceiling installations in builds or renovations where access is limited and a tool setup speeds the process. Maintenance or replacement tasks where clearance around the sprinkler is required without risking damage to the sprinkler. Overhead retrofit projects in commercial spaces with suspended ceilings where a secure, tool cage is advantageous.
