![]() But this is one way to approach that decision. It's really a judgment call that only you can make. This can be calculated.īottom line, it comes down to a judgement call: how much weight do you expect to put on the shelf and rod?Īlso, do you have children, and could they ever possibly try to hang from the rod or try to climb onto the shelf? If so, I'd use 4 brackets and #10 or 1/4 inch screws. Having all the load at the front edge creates more pullout load than having it evenly distributed, which is more than if its concentrated at the wall. Something to consider would be that the weight on the shelf and rod will be multiplied by the distance that the load is spaced from the wall. ![]() Pullout estimated at 340 and 440 pounds, respectively. Closet Rod & Shelf Brackets Brochure image 1195 Series Heavy-Duty Rod & Shelf Brackets Specifications KV 1195 Series Commercial Heavy-Duty Closet Rod & Shelf Bracket The 1195 Series heavy-duty fixed rod and shelf bracket is for use with closet rods with diameters of up to 1-3/8' and has a hook depth of 2-1/2'. I like the Hilti unhinged toggle with plastic, breakaway, through-wall member better than old-style hinged toggles.Īdd it all up, your estimated total shear strength for #8s would be 200 pounds and for #10s, 280 pounds. ![]() May cause injury, etc.ĭrywall anchors of both the toggle bolt and auger-anchor types might have a 40 pound strength, both shear and pullout, as it's typically the drywall that fails, though I've seen toggles fail at the hinge. This is entirely nonscientific and I am not an engineer, so this is all seat-of-the-pants, shade-tree mechanic type of stuff. Googling around, it looks like a #8 galvanized wood screw might have shear strength of at least 40 pounds and pullout strength of at least 150 and, for a #10 galvanized wood screw, 50 and 200 pounds might be a reasonable estimate. Also, the force at the bracket will include a torque created by the shelf's cantilever, so the force at the top screw will be a "pullout" while that at the bottom will be shear. So, 2, 3, or 4 brackets used will transfer the load to 4, 6, or 8 screws. Just guessing, I'd say 50 pounds per foot would be a maximum expected load, or 250 pounds total. That leaves the studs you've labeled 1-4. So, it might be difficult to get fasteners well-affixed into the available width. 2 Pack Ceiling Mount Bracket, Stainless Steel Wardrobe Pipe Bracket Rod Holder Ceiling Holder, ULIFESTAR Shower Curtain Closet Wardrobe Rod Lever Support. The corner studs probably are only half-exposed behind the drywall, as they are positioned to provide backing and a nailing/screwing surface for the drywall. The key to your question involves both mechanics and building practice. The short answer is, yes, it basically comes down to aesthetic.
