V-1 Reusable Temporary Anchor
The best, strongest, easiest to install temporary and reusable roof anchor we've ever used. Our patent-pending V-1 roof anchor is made in America of heavy duty stainless steel and TIG welded in an ISO 9001 facility. It meets OSHA 1910 and 1926 requirements when installed through roof sheathing into a roof rafter using (6) TimberLOK 4" hex-drive structural wood screws. Comes with 6 heavy duty fasteners and a hex drive bit. Recommended for best use with Petzl's triact-locking Vulcan or Oxan carabiners.
TimberLok 4" Structural Wood Screws are approved fasteners for installing the V-1 anchor through the roof sheathing into a suitable roof rafter. We recommend you order these through Amazon for about $100. Use each fastener only once for installing the V-1 anchor. Discard or repurpose for a different suitable use once removed. Do not use the same fastener again for an anchor installation because they have been weakened and are no longer compliant.
