Wind-lock ULP-302 Plates 1-3/4" 1M

ULP-302 Polypropylene Plastic Washers (1,000 per box) are 1-3/4" diameter, high-strength fasteners engineered for use in continuous insulation (Ci) stucco systems and ICF/SIP construction. Made from durable, high-grade polypropylene, these plastic plates are designed to flatten upon fastening, with built-in stiffening ribs to minimize deflection and improve hold.

Each washer includes 16 mechanical keyholes for locking base coat material, and can be screw-fastened, nailed, or shot, offering flexible installation across job site needs. The integrated engineered “flash” enables efficient pre-assembly with screws to reduce labor time.
