CheeMuii 16" Double Tender Spring Kit with 3-in-1 Stainless Air Lines Holder — Galvanized Spring & Rubber-Padded Holder

CheeMuii 16" Double Tender Spring Kit combined with a 3-in-1 stainless steel air lines holder secures, protects, and tensions trailer air hoses and power cords for trucks and semi-trailers.

Keep trailer air lines and electrical cords organized and protected with a durable spring-and-hook system built for heavy-duty over-the-road use. This kit pairs a galvanized carbon-steel extension spring and protective sleeve with a widened, rubber-padded 3-in-1 stainless holder so hoses stay tight, insulated from rubbing, and less exposed to weather and wear. It’s a direct-replacement style assembly compatible with a range of OE part numbers, designed to extend component life and reduce roadside fixes.

How does this kit prevent hoses from chafing and tangling?

The spring provides controlled tension so lines don’t sag or rub against trailer frames, while the protective plastic sleeve keeps the coil separated from hoses and cords. The 3-in-1 holder grips multiple lines and adds a rubber anti-slip pad to stop shifting during transit.

• Galvanized spring jacket protects against corrosion contact.
• Plastic sleeve prevents direct spring-to-hose contact and UV exposure.
• Rubber-padded stainless- steel holder secures three lines together without slipping.
• Widened 2" hooks fit large crossbars to avoid hook movement.

Will it fit my truck, trailer, or tractor application?

The kit is made for common heavy vehicle configurations and is a replacement for several OE references, so it matches many existing mounting points and line routing setups. Check compatibility by comparing physical hook width and spring length to your current assembly.

• 16" double tender spring length for standard tender setups.
• Replaces Tectran 9421-2, Automann 177.3007, Tramec Sloan 451748, Phillips 17-1482, Velvac 580071.
• 2" wide hooks and 9.5 mm thick carbon-steel hook for larger crossbars.
• Works with air hoses, gladhand lines, and electrical power cords on trailers and tractors.

How durable is the spring and holder in harsh conditions?

The spring uses high-quality carbon steel with a galvanized finish to resist rust and maintain elasticity under repeated load cycles. The holder is heavy-duty widened stainless steel with a corrosion-resistant painted surface and an anti-slip rubber pad to perform in wet and salty environments.

• Galvanized carbon-steel spring for rust resistance and long life.
• 9.5 mm thick hook material for increased load-bearing capacity.
• Painted hook surfaces and stainless holder minimize corrosion.
• Plastic protective sleeve prevents UV and weather exposure of the spring.

How simple is installation and what should I expect during setup?

Installation follows standard tender-spring and holder mounting procedures: hook the widened hooks to the trailer crossbar, route hoses into the 3-in-1 holder, and attach the spring assembly so lines are tensioned but not overstretched. Basic hand tools are typically sufficient and no special calibration is required beyond a secure attachment and correct line placement.

• Hook width designed to fit standard large-diameter crossbars for easy mounting.
• Pre-galvanized parts reduce the need for immediate corrosion protection steps.
• Protective sleeve slides over spring before routing lines to avoid pinching.
• Three-line holder keeps electrical and air lines organized in one bracket.

Who is this for: Fleet operators, owner-operators, and repair shops that maintain trucks, semis, and trailers looking for a rugged replacement tender spring and multi-line holder. It suits anyone wanting to reduce hose wear, simplify line routing, and replace worn original equipment with a heavier-duty, corrosion-resistant assembly compatible with common OEM part numbers.
