7075 Aluminum Locking Carabiner – 29kN

The A2109TN Aluminum Locking Carabiner’s material is 7075 aluminum alloy and offered with three locking options: Screw Lock, 2-Step Auto Lock, and 3-Step Auto Lock.

Featuring a specified 29kN breaking strength and a contoured aluminum frame, this model is designed for equipment manufacturers and outdoor brands seeking a choice of locking mechanisms.

The different locking options allow buyers to select a configuration based on their product requirements, preferred operating method, and intended application.

Key Features & Benefits

1. Three Locking Options – Flexible Solutions for Different Needs

The A2109TN series provides three locking configurations:

Screw Lock

A manually operated threaded sleeve allows users to lock the gate after closing. This design provides direct control over the locking mechanism.

2-Step Auto Lock

The automatic locking mechanism is designed to require two deliberate actions to open, reducing dependence on manually tightening a threaded sleeve.

3-Step Auto Lock

A three-action opening mechanism provides an additional deliberate opening step compared with a two-step design.

These options give OEM buyers flexibility when selecting locking hardware for different equipment and operational requirements.

2. 7075 Aluminum Alloy – Strength and Weight Balance

Manufactured from 7075 aluminum alloy, the A2109TN has a specified breaking strength of 29kN and a listed weight of 88.7g.

Its aluminum construction provides a high-strength material option for equipment manufacturers evaluating component weight, dimensions, and mechanical performance.

Weight and strength specifications should be verified for each locking version.

3. Contoured Frame – Practical Handling and Connection

The A2109TN features a contoured frame with recessed exterior sections and a locking gate assembly.

Its shaped body provides a defined handling profile, while the locking mechanism helps prevent unintended gate opening when correctly engaged.

The A2109TN series is offered with Screw Lock, 2-Step Auto Lock, and 3-Step Auto Lock options.

Q2: What is the difference between Screw Lock and Auto Lock?

Screw Lock uses a manually operated threaded sleeve, while automatic locking versions use a mechanism that locks when the gate returns to its closed position. Opening procedures vary by configuration.

Q3: Are the strength and weight the same for all three versions?

The supplied technical information specifies 29kN breaking strength and 88.7g weight. Exact specifications for each locking version should be confirmed individually.

Q4: Can we customize the color and logo?

Custom anodized colors and compatible logo-marking options can be evaluated based on order quantity and manufacturing requirements.

Q5: Can we request samples before placing a bulk order?

Sample availability, cost, and preparation time depend on the selected locking version and customization requirements. Contact our team for details.

Q6: Is A2109TN certified for climbing or fall protection?

Certification status must be verified for the specific locking version. A 29kN breaking strength alone does not establish suitability for climbing, rescue, or personal fall protection.
