Frequently Asked Questions
- Are cardboard corner protectors reusable? Many are designed for multiple uses, depending on handling and storage conditions. Reusability often depends on how well the corners hold their shape after folding.
- Will these protectors fit all frame edges? They fit common depths (1″, 1.5″, 2.1″ or 2.2″), but verify your frame dimensions before purchasing.
- Do they protect against moisture? Cardboard protectors primarily cushion edges; they are not a moisture barrier. Consider additional packaging for humidity exposure.
- Which option is best for bulk shipping? Larger sets (e.g., 120–200 pieces) with three-depth adjustability are generally better for warehouses and frequent shipments.
- Can I cut or modify them? Yes, most protectors are designed to be folded and shaped; avoid cutting as it may weaken edges.
- Do they affect framing quality? When properly applied, they preserve corners and reduce edge abrasions during transit and storage.
