Connectors

All connectors used in rope access should be of the double-closure type (e.g. screw-gate or screw-link), as these provide the required level of security from accidental detachment.

Where arboriculture (tree surgery) is carried out, connectors should be of the 'triple-closure' variety, in accordance with the arboriculture Code of Practice.

Steel connectors should be chosen when making attachments to other metal anchors — for example, cables, eyebolts and hangers.

Choosing the right shape & size

The connector should be of such a design and size that it is able to rotate freely on the anchor without hindrance, and without loosening the anchor or putting incorrect loading on the connector.

To avoid loading against the gate, it may be more appropriate to use a carabiner with a captive eye to maintain a lanyard or component in the intended position.

Suitably shaped 'Maillon Rapides' may be more appropriate where permanent or semi-permanent attachments are required, or where multi-directional loading may occur.

Standards

• Carabiner-type connectors: conform to EN 362. The standard requires a Minimum Breaking Load (MBL) of 15 kN, however BS 7985 suggests an MBL of 25 kN.
• 'Maillon Rapide' type connectors: conform to EN 12275 Q or EN 362.
