CHDT66 Aluminum Mud Flap Top Plate with DOT-2 Reflective Strip, 24" x 2-7/8" – Pack of 2, Pre-Drilled for Straight Hangers

CHDT66 Vehicle Exterior Guard is an aluminum mud flap top plate with pre-installed DOT-2 reflective strips designed to fit rear straight mud flap hangers and improve nighttime conspicuity.

Built for commercial trucks, this two-piece kit pairs a sturdy 24" x 2‑7/8" aluminum plate with 24" x 2" DOT-2 certified reflective tape already mounted for quick assembly. The plates accept straight-style hangers — whether spring-loaded or fixed — and are pre-drilled to speed up installation. These guards sit on top of existing semi mud flaps to add rigidity, a clean edge, and a visible reflective surface that meets regulatory-grade standards.

How does this guard fit my semi’s mud flap hanger?

The plate is sized and pre-drilled to accommodate rear straight-type mud flap hangers with lengths between 28" and 31.25". It works with common hanger designs, including both spring-loaded and simple fixed types, though minor adjustments may be required for less-common brackets.

• Aluminum plate measures 24" x 2‑7/8" for a consistent top edge.
• Pre-cut holes align with most straight hanger bolt patterns.
• Compatible with hangers 28"–31.25" in length.
• Professional installation is recommended for secure mounting.

What visibility and safety benefits do the reflective strips provide?

The kit includes DOT-2 certified reflective strips sized 24" x 2" that are adhered to the plate to increase visibility from the rear and side at night and in low light. DOT-2 grade material is commonly accepted for heavy vehicle conspicuity where reflective performance is required.

• Pre-installed DOT-2 reflective tape meets regulatory-grade visibility levels.
• Full-width 24" strip provides continuous reflectivity across the plate.
• Reflective surface reduces detection time for approaching drivers.
• Durable adhesive resists road vibration when properly mounted.

How easy is installation and what tools are needed?

>The plates come with pre-cut holes to simplify alignment with common hanger layouts, but exact fasteners are not included so you’ll need basic hardware. Installation is straightforward for someone familiar with truck exterior work, though a shop install ensures secure attachment and correct torque on fasteners.

• Pre-drilled holes reduce layout time and measurement errors.
• Requires basic hand tools: wrenches, drill (if holes need enlarging), and appropriate bolts/nuts.
• Use corrosion-resistant fasteners to maintain longevity.
• Professional fitting recommended for fleet vehicles or regulatory inspections.

Will this kit withstand road conditions and maintenance needs?

The aluminum construction offers a corrosion-resistant, lightweight top edge that stands up to regular road exposure; the reflective material is engineered for outdoor use. Routine inspections after heavy use or harsh weather will help keep the plate and reflective strip functional over time.

• Aluminum resists rust compared to steel top plates.
• Reflective tape rated for exterior use maintains retroreflectivity when clean.
• Inspect fasteners periodically to prevent loosening from vibration.
• Replace or re-adhere reflective strips if damaged by abrasion or chemicals.

Who this is for: this CHDT66 kit is ideal for fleet managers, owner-operators, and maintenance technicians seeking a durable, regulation-minded solution to enhance mud flap edges and rear conspicuity on straight-hanger semi setups. Choose this product if you want a pre-cut, pre-mounted reflective option that simplifies upgrade work on rear straight-type mud flap hangers while meeting DOT-2 reflectivity standards.
