Why Crews Choose This Premium Kit
Lighter Hardware, Less Fatigue
The 110VTB harness uses aluminum hardware throughout instead of stamped steel. The result is a noticeably lighter harness on the shoulders for full-day wear, with the same strength and corrosion resistance crews need on roofs that see weather.
Openable Rope Grab That Saves Setup Time
The RGSS58ES is the premium upgrade on this kit. Unscrew one screw, drop the rope in, screw it back. There is no threading the entire lifeline through the grab from the end, which matters when a crew is loading and unloading the rope grab between anchor positions all day.
A Bag That Works on the Roof
The MPBAG50 is not a plain duffel. It is a tool tethering and storage bag with six interior tie-off points and an exterior tie-back loop, so it can stay clipped on the roof during work as a fall protection bag for hand tools, not just a transport bag for the kit.
Suspension Trauma Built In
The harness ships with integrated suspension trauma straps. If a worker is held in suspension after an arrested fall, the straps deploy to relieve pressure on the femoral arteries and buy time for a rescue team to reach the worker.

How to Set Up and Use the Kit
The summary below is an overview. Always read and follow the full Frontline Roofer Kit user manual, calculate your fall clearance, and have a Competent or Qualified Person verify the setup before anyone works at height.
Inspect every component before use: harness webbing, stitching, and aluminum hardware; the RGSS58ES rope grab and shock pack; the VLP50 lifeline rope; and the RO01 anchor. Remove any defective component from service immediately.
Install the RO01 anchor centered over the roof framing on top of secured sheathing, no less than 6 ft from any exposed roof edge, using at least 22 of the included nails through the center and outer holes. The structure must support 5,000 lbs per worker.
Attach the VLP50 lifeline snap hook to the anchor D-ring. Open the RGSS58ES rope grab by unscrewing the side screw, set the rope in place with the arrow on the grab pointing toward the anchor, and screw the grab back together until it is fully closed and locked.
Don the 110VTB vest harness: dorsal back D-ring centered between the shoulder blades, chest strap at mid-chest, and leg straps snug. Confirm the suspension trauma straps are stowed and that the A marking is visible at the dorsal attachment.
Connect the shock pack lanyard snaphook to the harness back D-ring, confirm the rope grab locks when pulled sharply, work directly below the anchor to avoid swing falls, and keep a written rescue plan ready before anyone leaves the ground.
Important Use Notes
The RO01 anchor must be installed over secured roof sheathing, never directly to a rafter or truss, and never on rotten or degraded wood. Keep the maximum free fall to 6 ft and work no more than 30 degrees to either side of the anchor to limit swing fall. After any fall-arrest event, remove the harness, lanyard, rope grab, and lifeline from service and destroy them; the RO01 anchor must also be removed from service after a fall arrest. Inspect every component before each use and have a Competent Person formally inspect the kit at least every 6 months.

Frequently Asked Questions
What comes in the Frontline RK110V50 Combat Premium Roofer Kit?
The RK110V50 is a complete Personal Fall Arrest System with a premium upgrade across every component. It includes the 110VTB Combat Lite vest-style harness with aluminum hardware and integrated suspension trauma straps, the RO01 reusable roof anchor with nails included, a 50 ft VLP50 premium vertical lifeline, the RGSS58ES openable self-tracking steel rope grab with integrated shock pack, and the MPBAG50 vinyl tool tethering and storage bag with six interior tie-off points. Everything is sized to work together right out of the box.
How is the RK110V50 different from the RK5PTB and RK050V50 kits?
The three kits share the same RO01 roof anchor and the same 5/8 inch polysteel vertical lifeline, but the RK110V50 is the premium configuration. The harness upgrades to the 110VTB Combat Lite vest style with aluminum hardware and suspension trauma straps, the rope grab upgrades to the openable self-tracking RGSS58ES, and the bag upgrades to the MPBAG50 tool tethering bag. The RK5PTB Combat Roofer Kit and the RK050V50 Combat Roofer Kit are good options for crews that do not need the aluminum harness, the openable rope grab, or the tool tethering bag.
Is the RK110V50 kit OSHA- and ANSI-compliant?
Yes. The kit components comply with OSHA 29 CFR 1926 and 1910, along with the applicable ANSI standards: the harness meets ANSI Z359.11-2014, A10.32-2004, and Z359.1-2007, the RO01 anchor meets ANSI Z359.18-2017, and the vertical lifeline and rope grab meet ANSI Z359.15-2014. The RO01 anchorage connector was independently tested by SATRA Technology Centre to ANSI Z359.18-2017 on a simulated substrate and passed.
What is the weight capacity of the kit?
The kit is rated for one worker with a total combined weight of 130 to 310 lbs, including tools, clothing, and equipment. All five components share this range, so the system stays matched. If the combined weight of a worker and tools exceeds 310 lbs, the employer must modify the system to provide proper protection, as the standard kit is not rated for that load.
What kind of roof can the RO01 anchor be used on?
The RO01 is a hinged, reusable roof anchor that works on most roof peaks and flat surfaces up to a maximum pitch of 12/12. It installs over the secured roof sheathing, centered on the roof framing, using at least 22 of the included twisted nails (3.6-inch length, 0.15-inch diameter). It must be placed no less than 6 ft from an exposed roof edge, and never attached directly to a rafter or truss or to rotten or degraded wood. After removal, the roof penetration may need repair by the installer.
How does the openable rope grab work?
The RGSS58ES rope grab is built so the lifeline can be loaded without threading the rope from the end. To install, unscrew the single retaining screw, set the 5/8 inch polysteel lifeline into the grab body with the arrow pointing toward the anchor, and screw the grab back together until it is fully closed and the double-locking mechanism is engaged. The grab self-tracks up and down the lifeline as the worker moves and locks instantly under a sharp pull, with an integrated shock pack that limits arrest forces to 900 lbf.
How much fall clearance does the kit need?
Using the rope grab and lifeline system, the total fall clearance is approximately 18 ft measured from the anchor down to the nearest obstruction below. That figure combines the connector length, the rope grab deceleration distance, the energy absorber deceleration distance, the worker's height, and a safety factor for harness stretch. Always calculate clearance for your specific job and anchor height before working, and work directly below the anchor to limit swing fall.
