I just received some of these and they seem to be approximately the same as those used by some manufacturers.

Note: They might be stronger, so make sure that additional strength is not a problem for your application.

The 1" rare earth (or any magnet) are too wide. 3/4" or 1/2" work and are easier to sew in place. As far as being too strong ..... put two pieces of fabric between two rare earth magnets .... perfect.

To determine the size I just did some quick measurements using a tandem rig. The mating magnet for the main closing flap (whose magnet was missing) seemed like 1 inch. But also, maybe riser covers are a different size. That's the nice part about a company like www.apexmagnets.com, you can buy nearly any size (and shape) you want.

Another source that I have used. Quite a bit cheaper.

That link is to N52 grade. You probably don't need them quite that strong, but that's what I've used. This is the size UPT uses I believe. But any size you want is available here.

Always remember the brave children who died defending your right to bear arms. Freedom is not free.
