Cast brass, polished finish and two prongs in a 45 mm internal width. This buckle is aimed at wide leather belts where the hardware is meant to be seen. Brass keeps a warm tone and patinates over time, so a year on the belt no longer looks like it did the day you finished it.
- Two prongs spread the pull across two holes – the strap doesn’t twist around a single point under the buckle and the holes stretch more slowly. It shows on a belt worn tight every day.
- Cast, not bent from wire – the frame is one piece, with no joint that could be prised open. The 56 mm total length tells you how much room the buckle takes at the end of the strap.
- Prong ø 4.2 mm – punch the holes with a 5 mm hole punch #KEM/LSHP50, in two parallel rows at the same spacing. Uneven spacing is the most common reason a double prong buckle only fastens with a struggle.
- No roller – the strap slides over a fixed bar. On very stiff leather, tightening is noticeably harder than with a roller buckle.
The matching screw post for the belt is #SPH-4 BP.
TIP: Brass naturally oxidizes and darkens over time – it’s not a defect, just the metal reacting with air. You can restore its shine with #SITOL300G paste. To prevent darkening, apply the clear lacquer #637005/GLOSSY.

Frequently asked questions
Choose a buckle with the same or a slightly larger inner width than the strap. The number in the buckle's name is its inner width: a 38 mm strap fits a 38 mm buckle snugly and a 40 mm buckle with a little play.
Width: filter the belt buckle listing by inner width, for example buckles for a 38 mm strap.
Strap: our leather straps for belts are 38 mm wide, 3 or 4 mm thick and 1.4 m long.
Holes for the prong: the prong diameter is listed for every buckle; choose a hole punch to match.
Attaching: fix the buckle with Chicago screws so you can replace it later, or permanently with rivets.
