Guardian Fall Protection 00500 RIDG-1 Single D-Ring Roof Anchor with Nails 11-Inch in Length and 1 D-ring, 9¾"

It’s Durable, Safe, Heavy Duty and Good Quality. Easy to install on the ridge of the roof!

Good solution for installing permanent roof anchors. I use these for new construction or reroofing at intervals along a ridge for future safety lines. Stainless steel, placed under cap shingles so no water intrusion, should last as long as the roof does. Should be universally used, IMO.

Stainless, well made, comes with nails. You pop off the shingles and install this, then re-lay the shingle. Use a good shingle sealer/caulk. Get a good long shingle lifter--it makes the job easier and it can remove hidden nails too. Put a bit of silicon or ideally GeoCell 2300 in the nail hole as added leak protection.There is a cheaper version ($17) on Amazon but it says 7-10 weeks to ship. I just order 2 and I will update this post as to how long they actually took to arrive.We are a solar install company. We have decided to install these on all our clients homes.Update: the other anchor arrived in about 3.5 weeks

This definitely served the purpose. Any advice I could give is for metal roofs you'll want to place a square cut of thick flashing tape underneath the d-ring to avoid wear over time.

I'm using these as roof anchors for a power riser. The current "anchors" appear to be a heavily rusted thick screw and washer straight through the shingles and roof with a glob of tar on top. The roof is being redone and these anchors will be the new ones. Features I like: 1) Stainless steel (mostly, the ring is zinc-coated) 2) butyl strip to seal the nail holes. 3) included stainless steel screw nails, 4) thin enough for the shingles to lie flat on top, 5) offset design for the ring attachment that allows the anchor to lie completely flat. This is the only one I found to have all these features. I would also be comfortable using this for a personal safety anchor point.

I purchased two competing brands of permanent roof anchors. The Super Anchor Safety and the Guardian Fall Protection. The Super Anchor Safety cost less than the Guardian Fall Protection but it took two weeks to get the former. Both brands ship from Washington State. The pictures of the Super Anchor Safety here on Amazon does not convey the limitations of its product. When compared to the Guardian Fall Protection it becomes obvious which one has superior design and safety features. The Super Anchor Safety only has 6 holes for fasteners while the Guardian Fall Protection has 7. Both come with 8 spiral nails. The D ring on the Super Anchor Safety is limited on how high it could rise making it difficult to latch hooks. The loop that holds the D ring on the Super Anchor Safety has a shape that is not offset to one side. This prevents the anchor from laying flat on the surface. It makes water infiltration possible since the butyl strip will not come in full contact to the surface. In the end I kept the Guardian Fall Protection roof anchor and returned the Super Anchor Safety. The slight difference in price did not make it worth to compromise safety.

Heavy duty.

These anchors work great on the ridge of our shingled roof. The D-rings pivot freely so it's easy to clip-in and appear to be cad plated so it should not rust. I used additional poly sealant but the self-stick goo on the bottom side looks like enough to seal around the nails.
