These work exceptionally well - never release. I use a 10mm leather punch to get the exact size hold in my strap ends for the security locks.

There's only 1 flaw w/this product. You need to put a lock-washer with an inside diameter of a 1/4" guitar input jack under the hex-nut. This way, you won't have to worry about them coming loose (as much). Without the washers, I did tighten the hex-nut and they do come loose quite quickly. Now, I think I like these better than Dunlops because the strap doesn't stick out so far. I have Dunlop and Schaller, now. They both work, but I think the Schallers just look a little better.

I have straplocks on all my 70+ guitars and basses. I tried the Dunlop system but didn't like it. I use Schallers exclusively now. Beware of the immitations. Some are just poorly made, they are loose and can rattle badly. The cheap ones you can find from the far east are downright nasty. Plating is poor. Screw threads on the bushings are crude and nuts are a poor fit - they work loose. Worst of all, the mechanism sometimes doesn't even lock. Proper Schallers should also come with 2 sets of screws including extra-long ones. The twisting action of the two parts of the system can cause the buttons to work loose. I always use the long screw if I can and put a dab of glue on the threads as well. Search wisely and buy Schaller. You'll be grateful in the long run.

I value my instruments too much to not use a genuine Schaller German made strap lock. Saving a few bucks on a copy isn’t worth the risk of failure.
