That looks like the Nashbar cross fork.

If so;

The fork plate is glued onto the surface of the fork, and not with a particularly strong adhesive. unscrew the brake post and you can peel it off with almost no effort. The brake post - if tightened down enough - might pin it in place, but it might not. The entire brake boss assembly is remarkably flimsy.

I purchased mine for disc-brake applications, but was very surprised to discover how flimsy that brake boss was when I removed it. Made me glad I wasn't running cantilevers on that fork.

I will say though that as a disc brake fork it's been terrific.
