The
patented Multi Mark will help you get the perfect drywall cutout every
time with no measuring. It can be used for practically all electrical
boxes: metal, plastic, composite, rectangle, round, octagon, multi-gang,
single-gang, standard, or thin. Just insert the target in the
receptacle before hanging drywall. When you’re ready to cut the hole,
hold the Multi Mark locator magnet over the area where you think the
receptacle is located. When it finds the receptacle, the magnets will
snap precisely into place where the receptacle is located. Trace around
the locator, cut, then install. With the Multi Mark you simply put it up
once, cut the hole and you’re done.
