This has  proven a must have in windy conditions and has been field tested by HVAC Technicians
 
You get the 400 lb pull Gripper which has two 200 lb pull neodymium magnets and the Stabilizer which has one 200 lb pull neodymium magnet. Giving it a total of 600 lbs of pull. That pull is also going to depend on the thickness of metal it is attached to. The Stabilizer was developed to add support from side to side for the Gripper. This has solved most of the issues of the Gripper wanting to tilt due to high winds and wind gust.  The Stabilizer can be attached to either right or left side when using the top mount position and can be moved up or down at close to a 45-degree angle. When using the side mount it will have to go on the right side of the unit. We strive to make the Gripper as solid as we can but in certain conditions and how the Gripper is being used, there is always that chance it could still fail. So we encourage everyone to always use caution on high windy days.
The Stabilizer is powder coated same as The Gripper.
