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.

One of the things people forget is that there is a limited life to the sealed batteries in UPS battery back-ups, alarm systems, emergency lights and exit signs, and various other products. If it has been over 3 years you may want to consider replacing these batteries before there is a problem. At the very least overcharged batteries will fail when they are needed most. The batteries can also bulge and distort so they are very difficult to remove. Contact us to see how inexpensive it is to replace these batteries before there is a problem.
