RGSS58 Self-Tracking Rope Grab for 5/8 in Lifeline, 2-Pack
The Frontline RGSS58 is a moving rope grab for flexible anchorage lines: it tracks along with you as you climb up or down the lifeline, and locks instantly if a fall starts. The openable design installs mid-line in seconds - no threading from the rope end.
Machined from high strength alloy steel with a golden yellow galvanized finish, it runs on 5/8 in twisted rope or 15/32 in kernmantle, carries a 3,372 lb minimum breaking strength, and weighs 1.22 lbs. A unique anti-panic feature keeps the cam engaging even if the worker grabs the device in a fall. ANSI Z359.1-2007 and CSA Z259.2.5-12.
Who Needs This Product
This product is the connector between a worker and a vertical lifeline. Roofers, tower crews, and anyone climbing on a rope lifeline pair a rope grab with their harness and lifeline so the protection follows them hands-free. You still need the lifeline, a rated anchor, and a full body harness to complete the system.
Features
Self-tracking
Follows you up and down the lifeline without manual repositioning.
Anti-panic feature
Locks even if instinct makes you grab the device during a fall.
Openable body
Installs and removes mid-line - no feeding from the rope end.
Two rope sizes
5/8 in twisted rope or 15/32 in kernmantle.
Alloy steel build
Golden yellow galvanized for corrosion protection.
1.22 lbs
Light enough to forget it is on the line.

Match the grab to the rope. The RGSS58 is rated for 5/8 in twisted rope and 15/32 in kernmantle - the wrong rope diameter defeats the cam. Connect to the harness per the manual (short connection, dorsal D-ring) and verify the grab locks with a sharp downward snap before every climb.
