Installation Instructions

Internal Backer Plates (PDI-254I)

The 254I plates are for internal mounting, behind the drywall.
They are uncoated. Align the plates with the wall studs, as shown,
to use the slots in the four corners to mount the plate. See the
Mounting Options for information regarding the suggested fasteners
to use to mount the plate.

External Backer Plates (PDI-255E)

The 255E plates are external for mounting on top of the drywall.
They have a powder coated finish on the visible side. Align the
plates with the wall studs, as shown, to use the slots in the four
corners to mount the plate. See the Mounting Options for
information regarding the suggested fasteners to use to mount the
plate.

Mounting Options

For wood studs, the suggested mounting anchors are steel lag
screws for wood, meeting ASME B18.2.1 specifications and coated for
corrosion resistance.

For metal studs, use Hilti Toggler anchors sized for 1/4-20
fasteners with a minimum SAE grade 5 rated bolt. Install per
manufacturer’s instructions.
