CheeMuii 16" Single Tender Spring Kit with 3-Hole Clamp & 3-in-1 Air Hose Holder — Galvanized, Widened Hooks

CheeMuii 16" Single Tender Spring Kit is a heavy-duty spring assembly with a 3-hole clamp and a 3-in-1 air hose holder that secures and protects truck and trailer air lines and power cords.

This tender spring kit is engineered to keep airline and electrical lines tidy, tensioned and shielded from abrasion on trucks, semis, trailers and tractors. It combines a galvanized carbon-steel spring, widened hooks and a robust holder system so hoses and cords stay in place during heavy use and rough road conditions. The design replaces common OEM parts and focuses on long life and simple installation.

How does this spring kit protect air hoses and power cords?

The kit uses a galvanized carbon-steel spring to absorb movement and buffer strain, preventing sudden yanks that can damage fittings. A molded plastic sleeve and widened stainless-steel holder keep lines from tangling with the coil and reduce exposure to weather.

• Galvanized spring resists rust and corrosion for extended service life.
• Plastic protective sleeve prevents hoses from winding into the coil.
• Anti-slip rubber pad on holder secures hoses and cords together.

What components are included and how do they attach?

The package includes a 16-inch single tender spring, two heavy-duty widened hooks, a 3-hole clamp holder and a 3-in-1 stainless steel air lines holder with an anti-slip pad. Install by anchoring the widened hooks to the crossbar or bracket, clamping the hoses in the 3-hole holder and routing lines through the 3-in-1 separator.

• 16" galvanized carbon-steel coil for tension and buffering.
• 3-hole clamp for secure multi-line mounting with locking nut.
• 3-in-1 stainless steel holder with rubber pad to prevent sliding.

Will this fit my truck, trailer or specific OEM replacement needs?

The CheeMuii tender spring kit is built for a wide range of commercial vehicles and is compatible as a replacement for several common part numbers. Confirm measurements and mounting points to ensure fit, but the widened hooks and multi-hole clamp are designed to work with larger crossbars and standard airline configurations.

• Suitable for trucks, semi trucks, trailers and tractors.
• Replaces Tectran 9421-2, Automann 177.3007 and similar parts.
• Widened 2" hooks fit larger diameter crossbars without modification.

How durable is the kit under heavy use and weather exposure?

Durability is a focus: the spring uses high-quality carbon steel with good elasticity, then receives a galvanizing finish to limit corrosion. The stainless-steel 3-in-1 holder and painted hooks add mechanical strength and further rust resistance, while the plastic sleeve protects against sun and moisture.

• Galvanized finish reduces oxidation and extends life outdoors.
• Stainless steel holder resists bending and provides firm clamping force.
• Painted widened hooks provide extra corrosion protection on mounting points.

Who is this for: fleet managers, owner-operators and maintenance technicians who need a reliable, long-lasting tender spring solution to organize and protect air lines and electrical cords on heavy vehicles. If you want a direct OEM-style replacement with reinforced hooks, a non-slip multi-line holder and weatherproof components, this CheeMuii kit is designed to deliver straightforward installation and dependable service in commercial use.
