Gadgetzan Roof Safety Anchor,Permanent Roof Anchor For Fall Protection Connects To Wood Surfaces,Metal Roofing Anchor Use With Roofing Harness, Safety Ropes And Other Roof Safety Kit (Black - 5 Pack)

Very sturdy very heavy duty too heavy duty. The metal was so thick my clips would not fit in the hole, but if you had the right kind of clips, these would be highly recommended.

These steel roof anchors seem solid. At age 71, I decided to wear a roofer's harness when I need to climb on the roof.

A little tricky mounting on my metal roof. Worked perfectly

These work as they should. Low profile, permanent anchor.

These are strong and have more screw holes than I think are required. My only issue is that I am looking for a permanent anchor, and these will likely rust over time, even with a good powder coating. I will likely have to use these for attic anchors and keep them out of the weather.

Looks to be descent quality!

These are even thicker than I expected. With 9 holes for screws (properly installed to a rafter/truss and with appropriate length!), there is NO chance these would not hold even multiple tied-in persons falling off a roof at the same time. I am fairly certain the truss or rafter would fail before this bracket. On a previous roof I recently upgraded, I installed a ridge strap with D-rings on either side of the ridge (ASIN B01HIUAIRO). That matched the tan shingle color almost perfectly and is imperceptible from the street on a 2-story roof. Those straps were downright thin compared to this and they felt more than safe enough. For the roof I am about to redo, I picked this product because the roof is much lower to the ground and I therefore want to "hide" the anchor on the back side (not street side) of the roof. This also almost perfectly matches the shingle color I will be using. Equally important, there is a "step" in this product so the clip-in end of the anchor is held off the roof by about 1 inch. This will allow me and my help to tie in and not have the rope pull too strongly against any ridge shingles when working on the opposite side of the roof. Of course that issue is moot until the roof is completely finished, so it is more of a concern when clipping in for any future roof maintenance. I am very impressed with these. The gauge of them is about twice what I expected. No screws are provided in the package. I suggest "Black Head 25 PCS #10x4" Stainless Steel Phillips Pan Head Wood Screws" (ASIN B0CDKRH49F) just like I used with my other installation. There is NO chance a slightly thicker screw would fit the predrilled holes. The screw I am suggesting is stainless steel, so even if some of the bracket's electroplating wears off, no galvanic corrosive action should occur.

I know one reviewer was concerned about the lack of a material spec, and I agree that’s disquieting. If I were running a commercial roofing op, I might go with another choice for legal risk reasons. But holding these, it’s clear there is no way in the world this isn’t going to hold up if I slip on my roof and need it to arrest my fall. It’s super heavy, thick steel of some kind, and while I might think twice about trusting it to hold a fully loaded scaffold with 1000 lbs, it’s just no issue I can see at all for a single human. Tie onto two of them and it will be massive safety overkill.
