Black Diamond

Gridlock Carabiner - Screwgate

What Our Gearhead® Experts Are Saying:

"I reach for this biner anytime I’m belaying because its isolation feature actually works—my belay loop stays captured so the carabiner can’t twist or cross-load. The hot-forged shape feels dialed, the screwgate is smooth, and the rounded rope-bearing surface feeds slack cleanly. Once you’ve used a Gridlock-style biner, it’s hard to go back."

We trust the Black Diamond Gridlock Carabiner Screwgate whenever a clean, predictable belay experience matters most. Black Diamond built this uniquely shaped carabiner to stop cross-loading before it starts, locking the belay loop into its own isolated section so the connection stays oriented the way it should—no twisting, no shifting, no surprises at the anchor.

Hot-forged from 7075 aluminum with 25% pre-consumer recycled content, the Gridlock integrates an I-beam spine and a wide, rounded rope-bearing surface for smoother handling and reliable strength. The intuitive screwgate adds simple security, while the patented geometry keeps the belay loop exactly where it belongs. It’s a dependable, purpose-built tool that streamlines belays and boosts confidence on every climb.
