Poor quality control. Ruined a straightforward installation.
I installed this Arlington Adjustable i-Joist Bracket today to hang a new ceiling fan, and the quality control was incredibly disappointing.
The "ears" (the metal mounting tabs where the fixture screws thread in) were welded on crooked. Because they weren't straight, the mounting bolts were forced to enter at an angle. I spent a frustrating amount of time struggling to align the bolts through the fan's mounting plate.
Because the metal tabs were so unyielding, I couldn't even bend them straight. I ultimately had to modify a brand-new project by drilling the fan mounting plate's holes larger just to get the bolts to line up. A product designed for easy installation shouldn't force the customer to field-engineer a fix. Check your tab alignment before you get up on the ladder.
