Review on Heavy Duty Steel Picture and Mirror Hanger - Adjustable from 2-7/8 to 3-11/16 Inches - Pack of 2 - Prime-Line U 9131 by James Hodzic

Strong, durable, easy to install and set up. I use them regularly for large/heavy art installations and they are the perfect solution for large objects that need leveling. Anyone who has tried to hang a large mirror or piece of art using a clip or other means knows how difficult it is to get something on the first try. Even if it is level, an adjustment may need to be made depending on the visible irregularities in the wall, floor or ceiling. This greatly simplifies the work, since the adjustment can be made from both sides by lengthening or shortening the screws. I've used a few of these hangers for items up to 100 pounds and they've never let me down. I recently switched to another brand of prime line hangers because their packaging is more secure. Hillman makes a version of this hanger, but small parts, particularly small nuts, are routinely lost due to the company's poor and inadequate packaging. Prime Line hangers come fully assembled in packaging that will not be opened for shipping, so you're far less likely to lose the parts you need. It's also half the price of another brand, which is a significant difference when buying in bulk.
