Werk-Brau’s Manual D‑Lock Coupler is a fast, cost‑effective way to run a quick coupler without touching your machine’s hydraulics.

Instead of a hydraulic cylinder, this coupler uses a manual Acme rod. Grab a wrench or an impact, turn the rod, and the coupler opens and closes. There's no auxiliary plumbing, no hoses, and no added complexity.

This coupler features:

A mechanical front pin lock
A manual safety latch that prevents the Acme rod from backing off during operation
A dual locking design for secure attachment changes
A multi‑pin center design, giving dealers one coupler that fits multiple machine models and giving end users more attachment flexibility

Because it’s a manual coupler, attachments are connected and disconnected from the ground, not from the cab. For many applications, that’s a non‑issue. If in‑cab operation is required, Werk‑Brau also offers a dual locking hydraulic coupler option.

The Manual D‑Lock Coupler is built for 1 to 8 metric ton excavators, making it a compact, simple solution for operators who want reliability without hydraulic complexity.

If you’re looking for a secure, manual dual locking coupler that’s easy to use and easy to stock, this is worth a serious look.
