66 ELECTRICAL PRODUCTS CABLE PROTECTOR PLATE 1 1/2 INCH X 3INCH

Common Features:
Size: A #66 plate typically measures 1-1/2" wide x 2-1/2" tall, but the sizing can vary slightly by brand.

Material: Usually made of 16- or 18-gauge galvanized steel.

Installation: Hammered or nailed into the wood stud directly over the drilled hole where the wire passes through.

Usage rule: Required if the wire is within 1¼" of the edge of the stud (front or back).

Example Use Case:
If you're running a Loomex (NMD90) cable through a 2x4 stud, and the hole is too close to the front edge of the stud (less than 1¼”), you’d install a #66 plate over it to shield it from drywall screws.
