Wind-lock ULP-302 Plates, 1-3/4in Plastic Washer for Rigid Insulation, 1000/bx

ULP-302 Polypropylene Plastic Washers – 1-3/4" Diameter (Box of 1,000)

The ULP-302 Polypropylene Plastic Washers are high-strength fastening plates engineered for continuous insulation (Ci) stucco systems and ICF/SIP construction applications. Manufactured from durable, high-grade polypropylene, these washers are designed to flatten during fastening while built-in stiffening ribs help reduce deflection and improve holding strength.

Designed for efficient installation and long-term performance, each washer features 16 mechanical keyholes that help lock base coat materials securely into place. The integrated engineered “flash” allows for quick pre-assembly with screws, helping contractors reduce labor time and improve jobsite productivity.
