The plastic low voltage mounting plate solution
Erico has come out with MP1P, which will solve your problems with installing wall plates in “old work” applications. The MP1P has 4 raised dimples on the front to use as a guide to cut a hole into drywall. This will help reduce errors in getting the proper hole size. The only tools you will need is a dry wall saw and a screwdriver to attach the wall plate. Simplicity is the word that applies to using this product. It is fast, effective, and saves you money.
