Nails for 2 spacing strips

Bag with 7 grams (approximately 25) small nails. With these special thin iron nails, you can mount 2 spacing strips (10- or 11-frame) or 4 (6-frame) spacing strips. These nails have exactly the right thickness.

How to prevent the wood from splitting during assembly?
Place the head of the nail across the wood grain where the nail is desired. Give a small tap with the hammer to break the grain.
Pre-drilling a small hole is also an option. Then you can easily attach the spacing strips.
