Ernie Ball Strap Locks NI 4600

They're nice, I'm using them on my RS 620. Mounting them was a bit of a challenge since the screw holes in the RS 620 were not deep enough. Once I drilled deeper holes, all was good.

When I received them, I was a bit surprised about their size. The buttons are 2.5cm (1 inch) diameter and the ports are 1cm deep. That puts the strap around 1.5cm away from the guitar body.

Locking is easy and secure.

I bought these strap locks for my Epiphone LP last month and i am more than happy with them,

The quality is alright, could be more solid. The strap holder part (yk what i mean) seems to move around a small but when locked in and makes the strap seem like its going to come out, of course this wont happen but just something i noticed

These are a great choice of strap lock non the less, hope you find this review useful

Easy to install. Secure and easier to release than some other designs.

They work exactly as intended and seem very robust. They are quite prominent, so do be prepared for the bulkiness.
