These racks are already the strongest you can buy, but our customers have asked for a beefed-up, larger version for their stand up boards. Our answer is this solid oak base rack with 3/4" diameter, 24" long galvanized steel tube pegs, spaced at 10" on center (tilted up 10 degrees). This rack, carries our traditional semi-gloss, furniture finish and is BULLET-PROOF! It also incorporates our MODULAR design. This means that for additional storage, buy a second set, and stack sets to create four or six board storage. Then simply mount racks one set above the other Racks butt together and peg spacing remains constant. THEREFORE, STAND UP RACKS ARE SOLD AS TWIN RACK SETS ONLY. Mounting hardware is included.
