The applications of this cup magnet include magnetic holding, lifting, antenna Mounting, positioning, retrieving and much more.

  • Mail route strobe light anchor

    by Steve – 23rd Feb 2013

    My wife's jeep wrangler has a fiberglass roof. She needed a good magnet to hold her strobe light on. She uses it on a rural mail route. The magnet is on the inside of the roof. The light stays in place , even on rough roads.
