Checkmate FABX1-LE Leading Edge Self-Retracting Lifelines provide extreme confidence by utilising superior technology and craftsmanship in each unit to ensure that the user has maximum safety while working at height. The computer-calibrated and serialised digital braking technology is unparalleled, with each brake’s torque setting being individually set for optimum performance. The locking mechanism is designed to prevent nuisance lockups for increased productivity and automatically engages in the event of a fall while simultaneously activating an impact indicator to verify a fall has occurred.

The FABX1-LE housing is made of a tough polymer with recessed areas and smooth contours to protect labels and reduce size without compromising functionality. The unique shape of the lightweight thermoplastic housing provides an exceptional strength-to-weight ratio for ease of installation. This combination of high performance materials and a fully engineered design keeps the FABX1-LE both lightweight and durable.

The FABX1-LE has been tested and approved in a controlled facility for safe use over an edge with a 0.5mm radius or above, this however, does not negate the need for edge protection. Use over an edge should always be avoided where possible.

Independent Brake Pawls

The two Pawls work independently of one another, this ensures a “fail safe” capability if one should stop working.


Load Bearing Steel Chassis

The internal hot rolled steel chassis provides a structural metallic core beneath the external protective housing.


BCS Brush Cleaning System

The entry aperture has a pair of opposing brushes to minimise take up of debris into the device.


Carry Handle Attachment

Optional shoulder harness and carrying handle are available which can be easily fitted by the user.


Tactile Hand Grip

The red hand grip on the FABX1-LE allows the user to easily identify the block as a leading edge device.

Edge Rating

Leading Edge Rated

After extensive research and development the FABX1-LE has a leading edge-rating radius of 0.5mm or above.


Sealed Brake Module

The Brake Module is sealed by the use of “O” rings which stops water or dust ingress affecting the brakes efficiency.


Fall Indicator Hook

The ANSI-rated gate swivel hook includes a fall indicator, which clearly shows if the device has been subjected to a shock load.
