Schaller S-Locks M BC

Significantly better than the cheaper HB ones which tended to come loose for me, fits well on thick straps, and with the grub screws the nuts are sure to stay in place.
The locks are angled so that the strap can be connected to the buttons without pulling out the spring.
Only downside is that the screws themselves are attached to the buttons, so they can't be replaced by a screw that might fit better to existing holes.
Locks work with the buttons that the Harley Bentons comes with.

hög kvalitativa straplocks med lätta instruktioner och bra passform

I bought these having heard great things about them. And I get it now, These are way better then any of the alternatives on the market and the quality almost seems like its some sort of jewellery. Sadly they are quite expensive but I think its totally justified by how good the are.

Only drawback is if you use to play you guitar (or bass) in the "classical gutar position with left foot on a stool" the peg of the Lower lock will pierce your thigh.

Riktigt bra kvalité och toleranser vilket innebär inget skaller eller oljud när man rör sig.

Galen kvalitet som vanligt med Schaller.
För inget oväsen och är enkla att installera.

Rekommenderas varmt.
