Boa

The Boa is a high volume carabiner with a large gate opening and extended top bar, making it easy to clip with thick ropes and slings, and allowing it to accommodate multiple attachments.

Its asymmetric shape sits naturally in the hand for easy handling, and I-Beam construction means that despite its large size, the Boa is still relatively light.

Rigging carabiners are used at critical connection points in rigging and anchor systems. They are built to be strong, and have large gate openings, internal volumes, and extended rope baskets. This makes them easier to handle with gloves on, and allows them to accommodate thick ropes, and multiple knots or slings.

Boa product features

An overview of the features and benefits of the Boa carabiner.

Anti-Vibe
Anti-Vibe - Non auto-locking gate which requires two actions to open, resists being vibrated open, and is easy to use with one hand. Anti-Vibe screwgates are suitable in systems where the gate is at risk of opening due to vibration, but the simplicity of a screwgate is required.
Kwiklock
Kwiklock - Auto-locking gate requiring two separate actions to open. Kwiklock gates are suitable when auto-locking gates are a necessity, but rigging systems are relatively static and anchor points are easy to monitor.
Locksafe
Locksafe - An auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes or remote anchor points.
Screwgate
Screwgate - Non auto-locking gate which requires two actions to open, and is easy to use with one hand. Screwgates are suitable in systems where anchor points can be easily monitored and are unlikely to be affected by running ropes.
