QWORK Electric Magnetic Lock, 2 Pack 60kg 130LBs Holding Force Electric Magnetic Lock for Door Access Control System Electromagnet Fail-Safe NC Mode

Work very well. I see many reviews saying there's issues with strength and alignment. These magnets work with very short range, (tightly coiled) magnetic fields, so as soon as the plate gets any distance from the base (fractions of an inch) magnetic pull drops a ton. The plate needs to be kept clean. The spring loaded "popper" plastic pin needs to be able to retract fully into the plate (use the included allen key). And the plate should be mounted according to the directions, which have a single large bolt in the center with two rubber washers spacing the plate away from the doorframe. THIS IS SO THE PLATE CAN SELF-ALIGN to the magnet. If you crank the plate down tight, then any fraction of a degree of misalignment means it will lose significant magnetic force.

Happy customer. So far, no issues whatsoever and have used it outdoors for many months now.

This set of magnets is terrible, was going to use them as a safety for cabinets but they are hardly strong enough to retain the capture plate they come with. Just for giggles I increased to a 24.3v power supply, that helped but it could still be knocked off easily. Stay away from these, total garbage.

Works well. Only issue (not really an issue) is that it takes precise adjustment of the steel plate for it to stick. But once adjusted, it's great.

I am using these to hold 55lbs each and they barely hold, if the metal bar is not EXACTLY right, it will not hold.

The media could not be loaded. Works well. I assembled with a button switch for a demo. Just one of my units came with the housing chipped.FYI Screws are metric allen key 3 mmThere is a residual clamp depending on the surface area. A piece may not just instantly fall.

These are perfect for hiding secret doors, making the ‘magic’ happen!! Good quality and they hold up well against repeated usage!

We use these for dog traps, they work great!
