Common questions
How do the adjustable pre-scores work?
Three factory-cut score lines allow each protector to lock at 1/2", 1", or 2" depth. Simply fold the underside flap to your target depth, and the locking mechanism grips the frame corner securely. This single SKU replaces three separate products, cutting inventory overhead.
What ECT rating means for my stacking environment?
ECT-32 (Edge Crush Test) supports standard 4-5 tier pallet stacks in temperature-controlled warehouses. For higher-stack applications or outdoor storage, consult our technical team, we offer ECT-44 and ECT-48 options.
Will these protectors reduce my case cube or pallet density?
No. Since protectors ship completely flat, they occupy negligible space until assembled on-site. A full case (504 units) fits in a 12" x 12" x 8" footprint, adding minimal cost per frame protected and improving final pallet utilization.
Are these suitable for glass mirror shipments?
Yes. The rigid ECT-32 corrugated and locking corner grip are specifically engineered to prevent corner-to-corner frame movement and crushing during transit. They're industry-standard for mirror and glass-fronted art shipments.
