Key Features

  • Large 1-3/4 in. Plate: The 1-3/4 in. diameter plate provides broad bearing over insulation board and sheathing.
  • Ribbed Stiffening Design: Large ribs stiffen the plate and limit deflection once it is fastened in place.
  • Flattens When Attached: The unique plastic fastener design allows the plate to flatten out after attachment.
  • 16 Keyholes: Sixteen keyholes provide mechanical locking of the base coat into the plate.
  • Flexible Installation: The washers can be screwed-fastened, nailed or shot.
  • Bulk 1000-Count Box: Sold in a box of 1,000 washers for full-job coverage.
  • ICF Buck Attachment: For ICF/SIP work, use with Foam2Foam spray adhesive to secure wood bucks to form openings; pre-assembled versions with UWLM series screws are available from the manufacturer.

Coverage and How Much You Need

One box of 1,000 washers fastens a large EIFS or stucco board area; spacing depends on your system's fastener schedule, so plan washer count per board from the insulation manufacturer's requirements.

Fit and Compatibility

Designed for Wind-Lock EIFS/CI, stucco and ICF/SIP fastening systems, and can be paired with Foam2Foam spray adhesive for buck attachment. Pre-assembled versions with UWLM series wood/lite metal screws are available; standard screws, nails or pins for fastening are obtained separately.

Frequently Asked Questions

What is included in one unit?

One box containing 1,000 Wind-Lock ULP-302 plastic locking plate washers.

What are the washers made of?

They are made from high-grade polypropylene plastic.

How are they installed?

They can be screwed-fastened, nailed or shot through insulation into the substrate; the plate flattens once attached and its 16 keyholes lock the base coat mechanically.

What applications are they for?

They are engineered for EIFS/CI/stucco insulation attachment and ICF/SIP work, including securing wood bucks to ICF form openings with Foam2Foam adhesive.

How many washers do I need?

Follow your insulation system's fastener-spacing schedule; divide the total board area by the required spacing per washer to size the number of boxes.

Product Expert Notes

These 1-3/4 in. polypropylene plates are a standard choice for attaching EPS insulation board in EIFS and stucco assemblies because the ribbed design resists deflection while the plate flattens against the foam. Use them with Foam2Foam adhesive when fastening wood bucks into ICF openings to save field time. For jobs with pre-assembled screw expectations, look for the UWLM pre-assembled version to cut installation labor.

Wear eye protection when power-driving or shooting fasteners, and follow the substrate manufacturer's fastener-spacing and embedment requirements.

Order the Wind-Lock 1-3/4 in. plastic locking plate washers today and keep your EIFS, stucco or ICF job moving.
