Yes, of course. As standard, my straps come with a single 15mm wide floating keeper as shown in the store photography, but if you want a a fixed keeper it’s not a problem. I feel that 15mm is the perfect width for a single floating keeper, however it is too wide for a sewn in keeper so if you want a sewn in keeper it will be 9mm wide. A strap made with a sewn in keeper will also have a floating keeper (also 9mm wide).
If you want a sewn in keeper with your strap, please remember to let me know (either by commenting in the “additional Information” section when you get to the Checkout page, or by sending me an email immediately after placing your order). Unless you inform me otherwise, your strap will be made to standard spec i.e. with a single 15mm wide floating keeper only.
