Spring hook, metal

Sturdy buckle. Great.

For hungarian customers: Erős acél csatok, pont amilyen kell. Csak ajánlani tudom!

I bought 2 of then (should have bout 4 a least) to use them to some sort of cheap quick attachment on my platform (took the chance as I was not sure if the hooks fit on the endplate sling slots-then narrow ones placed on the lateral sides of the plate, as I was not willing to buy another endplate and/or attachments). It seem they work well as the hooks are flat not round so they can work. As for the quality they appear stronger in real life than in the pictures, and a bit bigger to. I would recommend them.
