Rare Ivory Oversize or "Oops" Sierra Uniline wallplate I have machined the opening for a standard Decora / GFCI size cutout in. 

This is the larger plate for covering wall defects measures roughly 5-1/4" x 3-1/2".

You will have trouble finding this plate at the hardware store!

Comes with screws.  Note these plates are 50+ years old and fragile.  Do not over tighten the screws or the plate will break! 

This is cut out for the standard -modern- rectangular cutout.  Will not fit the taller narrower Sierraplex triplex, Leviton Centura, or similar devices. 

Cutout is made by hand and edges may have some irregularities as do the vintage plates themselves.

One of these has a tiny corner defect in the opening, filled in and painted -see photos

Scuffs Oxidation and Wear. 

Sale is for wall plate and screws ONLY.
