- Hole size allows for extra wire, etc
- Up to one inch standard gap
- Installs firmly in wood, vinyl and aluminum
- Recessed magnetic contact

Larger than 3/8” but smaller than 3/4”, GRI introduces their newest innovative switch design, the one-half inch diameter, flush mount 150-12. This new design is in response to customer requests for a switch that would give them additional “working room” for extra wire, E.O.L. resistors, etc., yet would more readily install in hollow core windows. The 150-12 is a 1/2” diameter contact, manufactured from a special polyvinyl material with a unique collar design that will press into wooden or vinyl clad windows with a “snap-in” fit for hollow core vinyl or aluminum windows. The 150-12 is paired with a matching 1/2” magnet case to offer the installer a 1” gap. The 150 switch can also be paired with any of the wide selection of GRI magnets (including our MF-875) to help resolve difficult installation applications. Patent Pending.
