ITW Classic SR, 40 mm

The female side clicked in firmly on my first try, which was a relief after struggling with cheaper buckles in the past. The 40 mm size fits standard nylon webbing from my local hardware store perfectly.

I used it to replace a broken buckle on my camping bag, and the 40 mm fit perfectly with the webbing I already had. The side release mechanism clicks in securely and feels solid.

Snapped right onto my old 40 mm webbing and the click feels really secure. Just a heads up, you'll need the matching TG piece since the female side doesn't adjust on its own. Perfect for the pack repair I'd been putting off for months.
