Review on 🔩 Securely Mount Your Signage with 4 Inch Standoff Screws - A Durable Mounting Solution by Ronald Ingram

Heavy duty carrier. Works well so far and holds a heavy 6 x 3 ft with 1/4 thick tempered glass. I scanned the wall for 2x4 studs and then screwed them on. Important: After receiving the racks, I had to wait a few days when I placed an order: 8pcs LEROM Philips Screwdriver Set, including PH0 PH1 PH2 (Φ2.5 Φ4 Φ4.5 Φ5 Φ6) 3 inch because of thin screw Holes in those heavy duty shelves.
