Bought these straplocks, since I tried them they´re the only ones I use.
Much, much better than all others I have tried, including Fender and other brands. These can go on big padded leather straps, they have a big tolerance.
The golden ones are absolutely beautiful , stand out on photo/video and are available on other colours. The locking system is simple, efficient and reliable. Will buy again if I need another set. Actually even my spare strap has them - they´re that good !
