Should be standard

I really like the guitar button sliding into a slot on the guitar strap and then locking the botton in that slot.

It's like double security.

It was recommended to me over other options 20 years ago and all the electrics have them.

You can buy the buttons seperately so one strap can be used on many guitars.

Schallers are my favorite straplocks. Never had a failure.

Easy to install and remove. Look great. Save guitar dings and avoid broken headstocks. The only thing you have to watch for is loosening of the nut above the strap. If that occurs, finger-tightening again is all that is needed.

The only way to go!

Easy to use and totally strong, no fear of dropping anything with these babies!

Good product -- what you should know

These strap locks hold the strap securely on the guitar and they are easy to connect and disconnect. The strap button works as a standard strap button, so you can also connect a strap that doesn't have the locks.

You should know:

1. Unless your guitar already come with the Schaller buttons, like many Fender electrics, you will need to remove the existing buttons and install the Schaller buttons. If the old buttons use a different diameter or pitch thread, you will have to do a little fitting.

2. The diameter of the post on the lock is larger than most strap buttons. You may need to enlarge the holes in your guitar strap to fit the strap onto the lock.

3. The post on the lock is not long enough for very thick straps. It fits most straps well.

4. The nut on the lock can back itself out and drop off. You can lose the nut or, worse, have the strap disconnect from the lock. If you don't expect to remove the lock from the strap, secure the nut with Loctite or some other adhesive.

5. When the strap is disconnected from the guitar, be careful when you handle it so that the lock doesn't strike the guitar.
