The RGA10 is designed to provide vertical/inclined fall protection to operatives ascending /descending a ladder or structure. This version of the rope grab is for use with 16mm Hawser Laid Rope Only. This unit can be ordered with or without a shock pack that cannot be removed, however due to the "gate opening” method of attachment, the RGA10 offers positive closure and good camming action. The locking cam on this device is toothed and arrests well on the hawser laid rope. When used in conjunction with the RGA10R hawser laid rope, the RGA10 provides excellent protection as a vertical fall protection system.
