Thermal Insulation Pins

2"X2" Multi-Hole Perforated Base Insulation Hangers, Stick Pins for HVAC Duct Wrap & Foam Board

Product Overview:

When it comes to installing HVAC duct wrap, foam board, or fiberglass insulation on metal, wood, or concrete surfaces, you need a fastening system that is both versatile and rock-solid. Our 2"x2" Multi-Hole Perforated Base Insulation Hangers—also widely known as Stick Pins—are engineered to deliver exactly that. Featuring a large, square 2"x2" base plate with multiple pre-punched holes, these hangers allow for screw, nail, or rivet attachment to virtually any substrate. Paired with a sturdy steel pin, they provide a quick, tool-friendly, and highly reliable method to secure insulation materials in place, making them a favorite among HVAC contractors and industrial insulation fabricators.

Specifications:

Item: Perforated Base Insulation Pins
Material: Galvanized Steel, Stainless Steel, Aluminum
Base: 0.4x50x50mm
Nail Dia: 2.7mm, 3.0mm, 3.4mm
Nail Length: As your requirement
Accessories: Self Locking Washers, Insulation Dome Caps

Key Features & Benefits:

• Large 2"x2" Perforated Base: The oversized square base (50mm x 50mm) provides a significantly larger bonding and fastening surface compared to standard round-base hangers. This distributes the load evenly, preventing the hanger from pulling away from the substrate or tearing through soft insulation.

• Multi-Hole Flexibility: Equipped with multiple precision-punched holes (typically 4–8 holes), the base allows you to choose the optimal fastening pattern for your specific application. Use screws for metal studs, nails for wooden frames, or even industrial adhesive for concrete—ensuring maximum holding power in any environment.

• Premium Material Options: Available in Galvanized Steel (cost-effective, corrosion-resistant for indoor HVAC use) and Stainless Steel 304/316 (for high-humidity, outdoor, or food-grade environments). Both options ensure long-term durability without rust staining.

• Rapid "Stick Pin" Installation: Simply attach the base to the surface using your preferred fastener, then press the insulation board onto the pin. Secure with a self-locking washer or dome cap. No welding, no messy adhesives on the insulation side—just a clean, mechanical fix that takes seconds per pin.

• Versatile Insulation Compatibility: The pin is designed to easily penetrate and hold a wide range of materials, including fiberglass duct wrap, elastomeric foam boards, mineral wool, and acoustic panels. Perfect for both internal duct liner and external duct wrap applications.

• Vibration-Resistant & Maintenance-Friendly: Once fastened, the multi-hole base creates a rigid anchor point that won't loosen under HVAC vibration. The pin-and-washer system also allows for easy removal and replacement of insulation during equipment maintenance.

  
  

Typical Applications:

• HVAC Duct Wrap & Liner: Securing fiberglass or foam insulation to sheet metal ducts in commercial buildings, hospitals, and industrial facilities.

• Foam Board Insulation: Fastening rigid foam panels (EPS, XPS, polyiso) to walls, ceilings, and cold storage rooms.

• Industrial Pipe & Equipment: Holding thermal insulation on pipes, valves, and tanks where welding is not permitted.

• Building Thermal & Acoustic Insulation: Installing insulation on metal studs, decking, or concrete surfaces in new construction or retrofit projects.

• Marine & Offshore: Ideal for shipbuilding where "cold work" (no welding) is required and corrosion resistance is critical.
