Plasti-Grip® PBLP2 "low profile" is a 2" dia. high-density polypropylene washer used for attaching EPS foam board to various substrates. The closure fingers protect the screw, separating the base coat from the screw, recessed into throat chamber cavity. While the washer’s face becomes part of the lamina, screws secured to the substrate allow limited freedom through the washer’s center hole (lateral movement in the washer’s throat). The multiple keyholes in the washer’s face, allow excellent bonding with the base coat. The low profile feature allows attachment of ¾" or 1" foam. This allows setting the washer deeper into the foam (without "bottoming out") if the wall is not straight or greater rasping is necessary.
Applications
Attaching expanded polystyrene insulation (EPS) to all types of substrates for Polymer Based (PB) Exterior Insulated Finish Systems (EIFS).
Specifications
- Round 2" diameter plastic plate
- Multiple tapered slots for coating adhesion/bonding
- Screws, concrete anchors, self-drilling screws sold separately or assembled
Standard Features
- Can be screwed or shot. Cup holders mounted to safety stems of pneumatic, electric drill, or powder actuated tools. See details on this patented, efficient, and fast installation method.
- Bugle center hole with tolerance cross web to conform and hold pre-assembled screws.
- Low profile and reinforced tough design to hold EPS foam products.
- Reinforced radial ribs designed into the bottom section for strength and bearing support.
- Numerous grommet slot cavities allow exterior base coat to bond with disk face. Easy to handle, light weight, firm yet flexible.
- Unique, round plate design with outside circumference tapered flat. Round shape design, evenly distributes bearing load without any sharp edges, minimizing damage to EPS foam from dynamic wind forces.
- Seated plate has negative profile and will not catch edge of trowel nor interfere with exterior cladding, cement board siding, or acrylic PB EIFS systems.
- Approved and endorsed by major system manufacturers of exterior coatings, and insulation board / materials.
Cerification and Testing
ATI – York, PA, an independent test laboratory, per ASTM E-2357 for negative/positive load resistance, E-1667, E-283, E-330, and E-331 for water resistance, plotting the chart’s wind load data and determined suggested fastener spacing. MSDS and in-house test reports are available for your records.
