Costco Carabiner Multipack Review: A Deep Dive into Value and Limits
Costco, the warehouse giant known for bulk buys, occasionally stocks multipacks of carabiners, presenting a tempting proposition for anyone needing organizational hardware. But are these a smart purchase, and what can you realistically expect from them? This review cuts through the marketing to assess their true value and critical limitations.

Product Overview: What You Actually Get
Typically, Costco sells a multipack of 12 to 24 carabiners for a price between $15 and $30. The carabiners are usually made from anodized aluminum or coated steel, come in mixed colors, and feature a standard spring-loaded wire gate mechanism. They are often bundled with small accessory cords or sold as a standalone pack. The key specification to note is their load rating, usually printed on the packaging, which often ranges from 25 to 100 pounds (approx. 11-45 kg).
The Good: Where They Shine (Their Intended Use)
For their designed purpose—light to medium-duty general utility—these multipacks offer undeniable value.
- Exceptional Cost-Per-Unit: This is the primary appeal. You get a large quantity of carabiners for a low upfront cost, perfect for outfitting a household, workshop, or event.
- Adequate for Everyday Organization: They are perfectly suitable for:KeychainsOrganizing tools in a garageHanging water bottles or cooking gear on backpacks while hikingSecuring toys, pet leashes, or garden equipmentGeneral DIY and home projects
- Convenience: Having a stash of carabiners on hand for random tasks is genuinely useful.
The Bad and the Inconsistent: Noteworthy Drawbacks
Quality control in such high-volume, low-cost manufacturing is variable. Common user complaints include:
- Inconsistent Gate Action: Some gates may be very stiff, while others feel loose or "mushy" right out of the pack.
- Finishing Flaws: Rough edges or uneven anodizing are not uncommon.
- Spring Fatigue: Over time and with frequent use, the spring mechanism can weaken faster than in a higher-quality utility carabiner.
THE CRITICAL WARNING: What They Are NOT Designed For
This is the most vital part of the review. Costco multipack carabiners are NOT climbing, rappelling, or life-support carabiners.
- No Safety Certification: They lack UIAA or CE EN 12275 certification. They have not undergone the rigorous independent testing for strength (typically 20+ kN, or ~4,500 lbs), gate integrity, and durability that defines climbing gear.
- Material and Construction Unknowns: The exact alloy, heat treatment, and forging process are not held to the aerospace-grade standards of climbing hardware. Under a high-impact load (like a fall), they could deform or fail catastrophically.
- Gate Reliability is Unproven: A gate that accidentally opens under load (due to poor design or a weak spring) in a climbing scenario would be disastrous.
Using these for any activity where a failure could result in injury or death is extremely dangerous and irresponsible.
Comparison to Legitimate Climbing and Professional Utility Brands
- vs. Climbing Brands (Petzl, Black Diamond): No comparison. Climbing carabiners are precision life-support tools. Costco carabiners are disposable organizers.
- vs. Premium Utility Brands (Nite Ize, Heroclip): Brands like Nite Ize offer more thoughtful designs (e.g., locking gates, dual-gate S-biners) with better consistency and slightly higher load ratings for dedicated EDC use, but at a higher per-unit cost.
Verdict and Final Recommendations
For the right user, the Costco carabiner multipack is a good value—if expectations are properly set.
Buy them if: You need a large quantity of basic, disposable organizers for non-critical tasks around the house, for a craft project, a kids' activity, or a one-time event. Think of them as "single-use" or "light-duty" organizational hardware.
Avoid them if:
- You need carabiners for any climbing, rope, or safety-related activity.
- You require reliable, consistent performance for frequent heavy use.
- You are looking for a durable, long-term EDC solution (invest in a few higher-quality utility carabiners instead).
The Bottom Line: Costco’s carabiner multipack is the definition of "you get what you pay for." It solves the problem of needing many cheap connectors. It does not solve the problem of needing safe, reliable, or high-performance connectors. Always match the tool to the task, and for any task involving human safety, these are categorically not the right tool. Keep them on your keyring, not your climbing rack.
