Rescue M1 Aluminum Winch Line Recovery Shackle Black Anodized MetalCloak
MetalCloak Rescue M1 winch line shackle (patent pending). The load runs through the line itself, so the shackle's rating is the line's rating. 6061-T6 aluminium, black hard anodize, precision milled interior, roll pins to prevent pinching. Synthetic line up to 3/8in, works with a soft shackle or a 3/4in solid shackle. ⚠ Requires splicing the rope; the splicing tool is not included.
MetalCloak Rescue M1 — aluminium winch line shackle (black)
The end of a winch line is where damage usually starts. Conventional solutions rely on the durability of a pin holding the line. The Rescue M1 is built the other way round: it carries the load through the line itself, so the shackle's rating is the line's rating — there is no intermediate part that could turn out to be the weak link.
The manufacturer has filed a patent on the design.

? Read this first: the rope must be spliced
The manufacturer puts it at the top of the description: “The MetalCloak Rescue M1 Recovery Shackle requires splicing your rope. The tool to splice the rope is NOT provided."
That means the line has to be threaded and spliced — this is not a clamp-on or bolt-on terminal. If you have never spliced synthetic rope, plan it as a separate job or hand it to someone who does. The manufacturer allows about 1 hour.
Why it is built this way
- Rating equals the line's rating — the design introduces no narrower bottleneck
- Precision milled inside — a smooth surface under the rope loop, less abrasion and lower stress concentration
- Roll pins hold the parts aligned — the line does not pinch or fray
- Sits flush on the fairlead — it does not cant as the line spools in
- 6061-T6 aluminium — light, so it carries less energy than a steel hook if a line lets go
- Hard anodized — resistant to abrasion and scratching
What it works with
- Synthetic line up to 3/8in
- Soft shackles — the primary use; no metal-to-metal contact, less stress on your gear
- A 3/4in solid shackle — also permitted
⚠ The manufacturer notes: “Only for use with a Soft Shackle or 3/4in Solid Shackle."
Finish options
The manufacturer offers black and clear (grey) anodizing at the same price. This card is the black version — black hard anodizing is the more durable finish against scuffs and scratches. We can order the grey version on request.
