How to recognise it
Recognized as a vertical array of regularly spaced horizontal rectangular slots (typically ~10x3 mm at 1/2-inch intervals, often numbered) along a narrow roll-formed or stamped metal strip.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| Heavy-duty slotted wall standard slot (twin-track / double-slot standard) | Twin-track slots are longer vertical slots designed for cantilever shelf brackets rather than small horizontal clips in recessed pilasters. Twin-slot standards feature two parallel vertical rectangular slots per tier for cantilever brackets, whereas pilaster strips feature a single vertical column of horizontal slots for small shelf support clips. |
| Supermarket gondola upright slot | Gondola slots are much larger heavy-gauge vertical slots for structural shelving brackets rather than light cabinet clips. |
| 5 mm cabinet shelf pin hole | Pilaster slots are punched rectangular slots in a continuous metal strip/channel, while shelf pin holes are circular drillings (usually 5 mm or 1/4 in) directly in wood or cabinet casework. |
