CheeMuii 16" Double Tender Spring Kit for Semi Trucks — 3-in-1 Air Line & Cable Holder, Galvanized Heavy-Duty

CheeMuii's 16" Double Tender Spring Kit is a heavy-duty 3-in-1 holder that secures air lines and power cords on semi trucks and trailers while protecting them from wear and weather.

This kit combines two reinforced springs, widened hooks, and a molded protective sleeve to keep air hoses and electrical cords neatly tensioned and off the deck. Designed to replace several OEM part numbers, the CheeMuii kit is built for fleet and owner-operator use where durability, rust resistance, and secure mounting matter.

How does the kit protect air lines and power cords?

The spring action keeps hoses and cables suspended and reduces chafing where lines cross the trailer gap. Galvanized finishes and a protective plastic sleeve shield metal from the elements and prevent the spring from snagging wires.

• Galvanized carbon-steel spring resists corrosion and retains elasticity.
• Molded protective sleeve prevents wires from catching on coil windings.
• Anti-slip rubber pad holds hoses in place during vibration and travel.

Will the hooks fit different trailer crossbars and frames?

Yes — the kit uses widened, heavy-duty hooks sized to clear larger crossbars and frames common on modern tractors and trailers. The hooks are finished to reduce surface corrosion and maintain a secure grip under load.

• 2" widened hook opening fits larger-diameter crossbars.
• 9.5 mm thick carbon-steel construction for stronger load capacity.
• Painted and galvanized surfaces limit rust and prolong service life.

How durable is the spring under heavy use?

The springs are made from high-grade carbon steel for long-lasting tension and shock absorption. Galvanization and robust thickness allow repeated flexing and high-intensity use without rapid wear.

• High-tensile carbon steel provides consistent elasticity.
• Galvanized coating reduces rust even in wet conditions.
• Designed to buffer strain from moving trailers and rough roads.

What mounting and compatibility should I expect?

The CheeMuii kit is intended for a broad range of heavy vehicles and replaces several common OEM items. Installation is straightforward and the kit accommodates the typical hose-and-cord arrangements on semi tractors and trailers.

• Compatible with trucks, semi trailers, and tractors.
• Replaces similar parts from Tectran, Automann, Tramec Sloan, Phillips, and Velvac.
• Simple hook-and-spring installation requires minimal tools.

Who is this for? Fleet managers, owner-operators, and technicians who need a rugged, low-maintenance solution to keep air hoses and electric cords organized and protected will benefit from the CheeMuii 16" Double Tender Spring Kit. It’s useful for anyone replacing worn tender springs, upgrading to wider hooks, or standardizing hardware across multiple tractors and trailers.
