Amati Clamping Set (AM7377)
Set contains 12 clamps and 14 brass plates.
Attached photos show how to use these clamps: insert the photo-etched part on a normal stationery double clip, bend the fins and fix it in place. Fasten the clip onto the frame and check how it keeps the planking strip in the correct position, allowing a better gluing or nailing.
It can be used to keep in place different types of details, not only strips; you just need to check where to fix the clip.
