If you've ever looked closely at a well-made bag, you've probably noticed the metal label — sitting flat, centered, and perfectly secured. What you don't see is how it got there. This guide walks you through the full process, step by step. Whether you're a bag brand, an independent designer, or an OEM buyer, this guide will help you get it right every time.
What you'll need
Step-by-step installation
1
Straighten the prong feet upright
Make sure every prong on the back of the label is standing straight up. If any are slightly angled from packaging or handling, straighten them before moving on. This makes a real difference when it comes to getting clean, accurate holes.
2
Mark and pierce the holes
Hold the label against the leather in the position you want it to sit. Press lightly to leave a mark, then use a hole punch or piercing tool to create holes at each prong position. Taking a few extra seconds here saves you from misaligned holes later.
3
Push the prongs through
Align the label over the holes and push the prong feet through from the front of the material. They should pass through cleanly with light pressure. If you're meeting resistance, double-check that your holes are the right size.
4
Slide on the backing plate
Flip the material over and slide the backing plate onto the prongs from the back. The backing plate spreads the load across a wider area, which protects the leather and keeps the label sitting flat on the front.
5
Fold the prongs down to secure
Fold each prong down flat against the backing plate — from vertical to horizontal — so they lie flush and secure. You can do this with your fingers for most standard prong feet, or use flat-nose pliers for thicker ones that need more force. Work through each prong evenly so the label doesn't shift.
6
Check and done
Give the label a firm press from the front and a gentle tug to make sure it's not going anywhere. It should sit flat, feel solid, and show no gaps between the label and the leather. That's it — installation complete.
A few things worth knowing
Hole size matters
Holes that are too large will let the prongs shift around before you fold them. Match the hole size as closely as possible to the prong width.
Fingers vs pliers
For most standard prong feet, you can fold them down by hand. Pliers give you more control with thicker or stiffer prongs — just be careful not to scratch the label face.
Test on scrap first
If you're working with a new label style or unfamiliar leather thickness, always do a test run on a scrap piece before moving to the final product.
Match prong length
A prong that's too short won't fold down enough to hold. Too long, and it may poke through or damage the inner lining. Match them carefully to your material thickness.
