Attachment to Existing Terra Cotta

[gtrocks]

Has anyone ever used Hilti HY270 to attach a shear connection to an existing Terra Cotta exterior wall? We are supporting about 1000#. Hilti lists "hollow clay masonry" and some capacities, but I would guess that Terra Cotta is not what they mean. We were expecting the backup to be concrete masonry, not Terra Cotta. Thanks

I'd be hesitant to depend on Terra Cotta for anything structural - just me being a big chicken.

I understand it has moderate compressive strength but for shear and tension it's probably closer to dried snot.
