required or a separate site -specific engineering evaluation performed.
6. Aluminum components in contact with steel or embedded in concrete
shall be protected as prescribed in the 2015 Aluminum Design Manual,
Part 1. Steel components in contact with, but not encased in, concrete
shall be coated, painted, or otherwise protected against corrosion.

P = 46.0 psf
Cabinet
A= 60.9 sgft (entire cabinet)
Wall material: Wood CDX or equiv, thickness to match Min Embed
Anchor type/size: 3/8" Toggle Bolt (r)
Ref: Powers Strap -Toggle, catalog
Min Embedment: 0.5"
Min edge dist: 3" Min Spacing: 1.5"
Anchor tensile capacity: Tcap = 179.4 lb (per anchor)
Check Anchors for Pullout
Total Reaction: Rt = 2799 lb ... = P"A (entire cabinet)
No. of anchors req'd: n = 15.6 total anchors ...= Rt/cap
Total anchors required: 16 total anchors balanced over cabinet
OK, typical anchor option shown.
