Knape & Vogt Bracket 400mm 15.75" 5mm 3/4" 1200 Lb Steel White

Ok, I came across a sheet (4'x8')of 3/4" #1 plywood someone had sanded, stained and trimmed the edges out with 45* angles. Apparently it was used as a table top of some sort. I needed some long and deep shelves to hold my guitar amp and equipment in my room. I figured I'd have to fabricate a bracket system to hold all that weight on a very large shelf 2'x5' . But I gave a quick search here and there anyways. I kept seeing these knapp and Vogt brackets on every search I did. So I figured I'd try em. I found the cheapest place selling them to be Walmart, and I ordered them. They are extremely solid/heavy duty. These were coated in a gloss white finish that's very well applied and don't expect will ever scratch off. They're true to their listed dimensions within maybe the smallest tolerance out. I measured up my refinished plywood and secured the brackets at 32 inches apart and they lined well with the wall studs. They suggest a 3" screw to secure it but I used 2.5" and I am confident they're staying put till I remove them. Presently the shelf is holding my fender mustang 3 amp ,a small gallon sized humidifier, multiple amp cords, a few stomp boxes and various other guitar odds and ends.... I'd say altogether at least 75lbs. And it didn't flinch ! I could double or triple this weight I believe with no worries. They're quite a bit more expensive than the usual shelf brackets but for sturdiness they can't be beat. A pleasant surprise to get what you pay for , even if it is only a simple item.
