Checkmate Atom-X

ATOM-X is the smallest and lightest fall arrest block in its class in the world. Its lightweight chassis, PC ABS housing and webbing made with Dyneema® webbing contribute to its outstanding strength and performance.

The ATOM-X2 is a variant of the ATOM-X, which has an increased shock absorbing capability allowing the user to anchor at foot level. This is commonly refered to as a FALL FACTOR 2 situation.

By using a simple stainless steel yoke attachment system two ATOM-X’s can be linked together creating a dual or twin tail device.


  • PC ABS HOUSING - The high strength palmsize housing is robust and durable giving protection to the mechanical assembly and internal parts.
  • LOAD BEARING STEEL CHASSIS - The internal hot rolled steel chassis provides a structural metallic core beneath the external protective housing.
