400-XD National Door Xtreme Duty Lube -15oz Aerosol

400-XD is a product designed for extreme-duty lubrication, particularly for garage doors and operators:

• Purpose: 400-XD is an extreme-duty, non-silicone lubricant formulated for heavy-duty applications. It’s ideal for garage doors, operators, and other mechanical components requiring robust lubrication under tough conditions.
• Size and Form: Available in a 15 oz aerosol can, making it easy to apply with a spray mechanism.
• Key Features:
  • Penetration: Effectively penetrates frozen parts, threads, bearings, and metal surfaces, loosening stuck components.
  • Rust and Corrosion Prevention: This product protects against rust, corrosion, and the buildup of dust and dirt, which can impair door function.
  • Heavy-Duty Formula: Stronger than standard lubricants like the 400-HD, it’s built for high-stress environments and frequent use.
  • No Silicones: Safe for electrical components and surfaces needing painting, avoiding residue issues common with silicone-based products.
  • 3-Way Nozzle: This product features a versatile nozzle that adjusts from a mist to a stream with a quick twist, allowing precise application.
• Applications: Widely used by professional garage door service companies for tracks, springs, rollers, hinges, and bearings. It’s marketed as a "Tune Up In A Can" for its all-in-one maintenance capabilities.
• Availability: Sold by retailers like Preferred Doors LLC in Houston, TX, and online platforms such as Amazon and eBay. It’s often available in single cans or bulk (e.g., case of 12).
• User Feedback: While specific reviews for 400-XD are less common than for 400-HD, the National Door Lube line is praised for reducing noise, improving door operation, and lasting longer than alternatives like WD-40 or lithium grease. Some note a strong initial odor that dissipates over time.

This product is a step up from the 400-HD variant. It offers enhanced performance for extreme conditions, making it a go-to for professionals and heavy-use scenarios.
