Instant Keyring Carry for Your EDC Tools – Snaps securely into any magnetic 1/4" hex or 4mm bit socket, instantly turning your pocket tool into a keyring-ready EDC companion. Just click in and carry.

DUO Means Double Compatibility – The 1/4" shaft seats deep into sockets designed for double-ended bits, while the 4mm tube fits standard single-ended bit sockets — one insert that covers both standards seamlessly.

Wide Compatibility Beyond the 711L Ecosystem – Works with Pen Driver TS/TG, Mini Ratchet Wrench TG (#71143), Mini Ratchet DUO (#71146) and 1/4" Magnetic Bit Extension (#7AX1C), plus any third-party tool with matching sockets.

The Starting Point of Your Personal EDC Ecosystem – Every 711L tool works great solo. Connect them and the magic happens. The Keyring Loop DUO opens up a modular, expandable toolkit tailored to your lifestyle.

Precision-Machined in Taiwan by Tool Enthusiasts – Built from solid stainless steel to match the fit, finish and durability of every tool in the 711L lineup. Compact, refined, and built to last.

Your Tools Deserve to Go Where You Go Most people don't carry enough tools because carrying tools is inconvenient. The 711L Keyring Loop DUO solves that in the simplest way possible — it turns any compatible pocket tool into a keyring attachment, so your favorite screwdriver or ratchet wrench is always on you, no pouch or bag required. Small enough to ignore, useful enough to miss when it's not there. Each loop slides into either a 1/4" deep hex socket — the kind designed for double-ended bits — or a standard 4mm single-ended bit socket, held securely by the socket's own built-in magnet. No extra parts, no threading, no fuss. Works with the 711L Pen Driver TS, Pen Driver TG, Mini Ratchet Wrench TG, Mini Ratchet DUO, and 4mm Micro Ratchet Wrench — and any third-party tool that shares the same socket standard. You get two loops in the pack, because one good tool is never enough. Equip two tools across your keyring, bag, and belt loop and you're ready for whatever the day throws at you — a loose screw at the office, a trailside adjustment, a quick fix in the field. If you're building a personal EDC toolkit that actually works together, this is where many 711L users start. Each tool in the ecosystem is designed to connect, complement, and expand the others — and the Keyring Loop DUO is the link that keeps your favorites within reach at all times.
