Jonard Tools TTBW-158 Steel Barrel Fastener Plunger Tool Bundle

Our review of the Jonard Tools TTBW-158 finds it to be a focused, practical toolset for technicians who routinely service water utility barrel locks. The bottom line: this bundle is built around a hardened plunger tool that is specifically made to open Highfield #6 barrel locks with a 0.158 in inside diameter, paired with an ergonomic can wrench that reaches into confined spaces. It is best for field crews and contractors who need a compact, heavy-duty key and a versatile can wrench, but not for anyone who needs broader lock compatibility.

Key Features

• High carbon alloy steel construction: The plunger tool is made from high carbon alloy steel for heavy-duty use and feels solid in hand for repeated service calls.
• Precise fit for 0.158 in locks: The tool is designed to ONLY unlock Highfield 93180128 and 93180124 #6 locks, ensuring a reliable fit for those specific fasteners.
• Smooth plunger operation: A heavy-duty spring and smooth plunger action help the key engage and unlock consistently when used on the intended barrel locks.
• Ergonomic can wrench handle: The can wrench has a 7/8 in diameter thermoplastic handle shaped for comfort during long jobs and torque transfers.
• Deep sockets for tight areas: The 7 in can wrench includes 1 1/4 in deep sockets to access recessed or hard-to-reach fasteners without extra tools.

Who It's For

This bundle is aimed at utility technicians, water district crews, and contractors who frequently encounter Highfield #6 barrel fasteners with 0.158 in inside diameters and need a dedicated, durable key that will fit those locks precisely. The included can wrench suits technicians who must access deep binding posts and need a comfortable handle for repeated use.

Those who should look elsewhere include anyone who needs a universal barrel lock key for many different manufacturers or meter brands, since this plunger tool is intentionally limited to Highfield 93180128 and 93180124 #6 locks. Also consider alternatives if long-term extreme-duty use is expected and a fully guaranteed unbreakable tool is required, as some users reported mixed build longevity.
