DIY Frequently Asked Questions / Shelf Standard')">
Pre-slotted metal strips attached to the wall, preferably into wall studs.
Can be attached with toggle bolts or similar fasteners approximately 16” apart.
If the standards are further than 16” apart, the shelves may not support heavy loads.
A newer variation includes a mounting rail that is fastened across the studs. The standard then clips directly into the rail or may require an adapter. Usually requires a fastener at the bottom for stability.
