A wall-mounted board with threaded-pipe pegs that gets your Olympic plates off the garage floor and organized by size — a horizontal stud-mounted rack built entirely from hardware-store plumbing parts, following Testify Strength & Conditioning's build.
Play Testify's linked video end-to-end first — it walks the whole stud-mounted board, flange, and threaded-peg layout. Decide how many pegs you need and their spacing: space them far enough apart vertically and horizontally that a fully loaded peg of large bumpers clears the pegs around it.
Cut the 2x6 to length so it spans at least two studs (16" apart on standard framing; three studs / ~32" is even more solid). Sand it smooth, then prime and paint if you want the finished look from the video. Let paint fully cure before mounting.
Clamp each 12" threaded nipple and cut it in half with a hacksaw or pipe cutter to make two 6" pegs — three nipples give you six pegs. Each piece keeps one factory-threaded end (that end goes into the flange).
Mark the six flange positions on the board face and pre-drill pilot holes. Fasten each flange with four short wood screws, then thread a peg (factory-threaded end first) into each flange — hand-tight plus a snug quarter-turn with the wrench.
Find and mark your studs with the stud finder. Hold the board level against them, drive one construction screw per stud at the top, re-check level, then drive the rest — two 3/8" × 4" screws into each stud. Every screw must hit solid stud framing.
Load your lightest plates first, one peg at a time, and watch the board for any pull-away from the wall before adding your heaviest plates. A solid mount won't flex — if it does, add another screw into the studs.
