Carabiners & Connectors

Carabiners for tree work from the world's top brands - Petzl, DMM, ISC, SMC, and more.

Climbing carabiners must be self-closing and self double-locking.
Ansi-gate carabiners are gaining popularity for the extra security of the reinforcecd gates.
Steel carabiners are useful in climbing and rigging, when strength and durability matter most.
Non-locking carabiners are popular for tending devices, holding saws, slide lines, and more.

Carabiner Locking Types

The ANSI Z133 Requirements for Safety in Arboricultural Operations outline the requirements for carabiners used in climbing and work-positioning systems.

Different manufacturers use different terminology, which can sometimes be confusing. Some will count the number of actions used to open a gate, including the final pull-back, and some will only count the locking steps. This is why you'll see TriAct or double-locking sometimes used to describe the same locking type.

To keep it simple, we stick with 'Double-Locking' to refer to a carabiner that uses 2 or more locking steps and meets the ANSI requirements.

Carabiner Shapes

There are 3 main carabiner shapes:

  • Oval Carabiners are great for climbing systems used in tree work. The more or less symmetrical shape keeps hardware vertically aligned and centered. These carabiners are well-suited for use with the mechanical friction devices used in three climbing.
  • HMS / Pear-shape carabiners have a larger, more symmetrical top makes for a larger gate opening & easier attachment to other hardware. In tree work we often recommend these for flipline and lanyard attachment.
  • D carabiners have an asymmetrical shape that keeps load oriented more along the spine, for a generally stronger design.

Carabiner Dimensions

This illustration shows how carabiners are measured for height, width, and gate opening.

  • Height: Length of main axis (A)
  • Width: Width at widest point (B)
  • Gate: Width of gate opening (C)

ANSI Z133 Requirement

Carabiners used for climbing or work positioning must be self-closing and self-double locking, and capable of withstanding a 5,000 lb (22.24 kN) load along the major axis with the gate closed. See ANSI Z133-2017 8.2.8.

We stock TONS of carabiners and connectors. Quickly sort by gate type, brand, material, and shape uses the links to the left.

Double-Locking Carabiners: self-closing & self-double-locking, with at least 5,000 lb. MBS. This meets the ANSI Z133 standard for connector that will support a climber. You may hear these carabiners called auto locking or positive-locking.

Screw-Locking Carabiners: perfect for rigging and setting up redirects. A screw-locking gate is not approved for the primary support of a climber in tree work.

Non-Locking carabiners: come in all shapes and sizes, from large paddle carabiners perfect for racking a saw, to tiny accessory 'biners to tend an SRS system.

ANSI Gate Carabiners: these locking carabiners meet the ANSI z359.1 standard for fall-arrest connections, with a MBS of at least 16kN strength on all axes, even side-loaded.

Steel Carabiners: increase strength and durability along with weight. Many uses in rescue and rigging.

Carabiner Keepers: keep your hardware positioned correctly on slings, lanyards, and more.
