This invention is a device to improve the safety of rock climbing and mountaineering participants by use of a reactive joint that allows the simultaneous opening of both gates of a double gate carabiner by manipulation of the action gate that results in the opening of the reaction gate in concert with the action gate, resulting in both gates being opened with only one hand movement by the climber.

A snap hook includes a body, a gate, a connection link, and a coupling. The body has a central portion positioned between an upper portion and a lower portion. The gate is pivotally coupled proximate the central portion. The gate and the body selectively form a closed configuration that defines a hook connection passage and an open configuration that provides access to the hook connection passage. The connection link has an upper end pivotally coupled proximate the central portion of the body and a lower end including a body connection aperture. The coupling interconnects the lower end and the lower portion. The coupling is configured to break when a select amount of force is applied to the lower end and release the lower end from the lower portion to redirect the select amount of force from the lower portion to the central portion of the body.

A snap hook that includes a body, a gate, a connection link and a breakable fastener is provided. A central portion of the body is positioned between an upper portion and a lower portion. The gate is pivotally coupled proximate the central portion of the body. The gate and the body selectively forming a closed configuration that defines a hook connection passage and an open configuration that provides access to the hook connection passage. An upper end of the connection link is pivotally coupled proximate the central portion of the body. A lower end of the connection link includes a body connection aperture. The breakable fastener couples the lower end of the connection link proximate the lower portion of the body. The breakable fastener is configured to break when a select amount of force is applied to the lower end of the connection link to transfer the force from the lower portion of the body to the central portion of the body.

Embodiments are directed to a carabiner that includes a carabiner body forming an opening having a width, the carabiner body including a gate rest notch, a gate rest and a long side, with the opening opposite the long side. The carabiner further includes a pivotable gate coupled to the carabiner body at a pivotable point and adapted to contact the gate rest notch when in a closed position. The opening includes a first side and a second side, the first side including a first angle that is non-perpendicular to the long side of the carabiner body and the second side including a second angle that is non-perpendicular to the long side of the carabiner body.

A dual hook device having both a grab hook and a sling hook connected to form one device for hooking chains, ropes, and cables and is capable of lifting heavy objects.
