I'm framing a couple of mirros that will run 60 to 70 lb ea. I'd like to use WB's for ease but wonder if they will bend under the weight? Has anyone used them succesfully (or not) for pieces this heavy?

The published limit for WallBuddies on their own hooks is 60 lbs. Over that, screw anchors are recommended.

But personally, for 2-point hanging of that kind of weight I'd be as much concerned about the wall failing as the frame hardware.

My choice would be the Z-shaped aluminum extrusions that come in lengths, cut to fit your frame. I suggest using screw anchors every 18" to 24", or screwing into at least three studs behind the mirror.

It isn't normally necessary, but for a very heavy mirror, you could use the z-bars on both the top & bottom rails of the frame, making sure the top one is slightly looser. That is, the main support comes from the bottom one, and the top one keeps the frame from falling forward. The top also acts as a safety, in case the bottom pulls out of the wall.

ditto jim, on the z-bar. 'cept when we do top and bottom we make 'em either same tautness or bottom a wee loose. loose tops rattle a bit.

Having the load on the bottom rail removes gravitational stress from the frame corners. When the top rail carries the load, frame corners could fail over time.

The top Z-Bar won't rattle if you pad the connection of the aluminum parts. I have used a few patches of Volara foam tape (used to line frame rabbets to keep canvas art from sticking).
