CLASSIC MECHANICAL HORN ACTIVATION
Bring authentic, tactile control to your commercial or heavy-duty pneumatic setup with the premium Kleinn Model 311 All-Brass Hand Pull Lanyard Valve. Explicitly engineered to interface with roof-mount air horn systems, this mechanical valve bypasses electronic solenoid wiring entirely, allowing you to manually meter and unleash the full force of your air horns with a classic lanyard tug. Featuring a solid all-brass structural body, this heavy-duty valve delivers a zero-lag pneumatic response, providing an instantaneous, reliable blast every single time the cable is pulled.
DIRECT ROOF-MOUNT INTEGRATION
The Model 311 is designed for a clean, secure physical install, threading directly into the base of your roof-mounted horn trumpet assembly. Outfitted with a high-pressure 1/4" Outside Diameter (O.D.) compression tube inlet, it establishes a leak-free plumbing line directly from your onboard air tank loop. Engineered specifically to match Kleinn's flagship roof-mount multi-bell lineups, this durable, non-locking spring-return valve returns instantly to the off position the second the lanyard is released, protecting your air supply from accidental drop-offs.
THE VERDICT:The definitive mechanical valve for classic roof-mounted setups. The Model 311 combines rugged all-brass durability with a simplified plumbing profile to ensure your roof horns trigger instantly with a simple, authoritative pull.
🔴 PRO TIP: Prevent slow system pressure drop-offs and phantom leaks at the roofline. When threading this mechanical valve directly into your roof-mount horn base, always apply a precision bead of liquid anaerobic thread compound like our genuine Kleinn JUICE to create a permanent, vibration-resistant structural seal.
