Rapid Lock-on

The brake activates quickly under the acceleration of the user and triggers the Pawl to lock onto the shaft.


Webbing & Shaft

One piece shaft supports the Dyneema & Polyester webbing which has a minimum breaking load of 15kN.


PC/ABS Housings with Grips

High strength housings give protection to the mechanical assembly and include TPE grips to both sides.


Shock Pouch

The shock pouch reduces peak shock loads to less than 6kN and extends to varying amounts depending on the fall conditions.


Dual Adaptor

A simple coupler connects two FAB3W’s which can be mounted on the rear "D" of a full body harness giving the user two attachment points for greater safety in the workplace.


Fall Indicating Swivel Hook
