What is the difference between Universal Wall Standards and Heavy Duty Wall Standards?

Universal Wall Standards (W40-) use 1/2" slots on 1" centers — the most common pattern in North American retail, compatible with the widest range of brackets and accessories. Heavy Duty Wall Standards (W700-) use 1" slots on 2" centers — a heavier pattern engineered for higher merchandise loads. Accessories are NOT interchangeable between the two slot patterns. Choose Universal for general retail merchandise; choose Heavy Duty for footwear display, boxed goods, hardware, dense merchandise, or any application where bracket loads will be significant.

How does an outrigger system work — does it put all the weight on the wall?

No — that is a key advantage of outrigger systems. The outrigger post mounts to the wall at the top and bottom, with the lower attachment resting on the floor. This transfers merchandise weight to the floor through the post, not to the wall. This makes outrigger systems suitable for walls that cannot support heavy shelf loads directly — drywall, older construction, or walls without stud access at every required shelf position.

How do I tell which slot pattern my existing wall standards have?

Measure the slot width and the center-to-center distance between slots. Universal: 1/2" wide slots, 1" center-to-center. Heavy Duty: 1" wide slots, 2" center-to-center. You can also count slots per foot — Universal has approximately 12 slots per foot; Heavy Duty has approximately 6 slots per foot.

Can I use my existing slatwall accessories on an outrigger system?

Standard slatwall hooks, brackets, and faceouts are NOT compatible with outrigger slotted post systems — they engage slatwall grooves, not slotted standard holes. Use outrigger-compatible accessories: tube brackets (WCR, WCR1, WA212), shelf brackets (RS-W8114, W8112), hangbars (PO-HBAR), and faceouts specifically designed for the outrigger slot format.

What spacing should I use between wall standard uprights?

Standard retail spacing is 24" on-center for most shelving applications. For shelves 4 feet wide or longer, add a center standard at 24" intervals to prevent shelf sag. For glass shelves, space standards no more than 24" apart. For hangbars and faceouts with lighter loads, 36"-48" spacing may be acceptable — contact our team at 800-571-3301 for guidance on your specific application.
