OVERKILL Heavy Duty Carabiner

Absurdly Strong Heavy Duty Carabiner

If you need to hang something very heavy, this is for you.

Designed to hold heavy objects for long time periods. Very durable and doesn't flex under 30kg, can hold a lot more. 

Use filaments like PETG, Nylon or PC, because they're not brittle. ABS or PLA isn't a good fit for this.

WARNING: Do not use for climbing.
