SKU:WUS950/970
Turn open hopper-front bins into enclosed, dust-resistant compartments with Quantum WUS clear windows. Each window slides into the hopper opening of its matching Ultra Stack & Hang bin or 24"/30"/36" HULK container, holding small parts securely inside while keeping the contents fully visible — ideal for high bins, mobile carts, and anywhere product might spill or wander.
Windows are made of durable clear polymer and install in seconds without tools. Sizes below are matched to the bin or container model they fit; most are supplied in multi-packs, and the large HULK sizes are sold individually. Bins and containers are sold separately.
Most items ship in 1–3 business days; special-order and drop-ship items vary by vendor.
Does shipping cost extra?
Freight depends on which supplier ships the item. Your cart shows each shipment's freight and any free-freight threshold before you check out.
Can I get a better price on a larger quantity?
Larger quantities often price lower. In your cart, use "Request a quote for this cart" (or our Request a Quote form) for a volume price.
How can I pay?
By card at checkout. ACH or check is accepted on invoiced orders, and Net 30 terms are available for approved business accounts.
What if something arrives damaged or wrong?
Tell us within 7 days of delivery, with photos and your order number, and we will replace it or refund it at our cost. Items you no longer want can only come back with prior approval, within 14 days, unopened, with a 20% restocking fee, and the buyer pays the return freight. Custom, opened and hazardous items, and chemicals and adhesives once shipped, cannot be returned. Details are in our Refund & Return Policy.
