Buying Guide
Key factors to consider when choosing cardboard corner protectors:
- Frame compatibility: Check the maximum corner thickness the protector supports (commonly 1″, 1.5″, 2.1″ or up to 2.2″). Choose a model that fits your typical frame sizes.
- Material and durability: Look for thick, multi-layer corrugated cardboard for better impact resistance, especially if items are shipped or moved frequently.
- Adjustability: Cards with three-tab slots or multi-depth options provide versatility across different frames and artwork.
- Quantity vs. reuse: Larger packs save per-unit cost and allow reuse for many projects, but ensure you can store them flat when not in use.
- Ease of use: Flat-pack designs with clear folding instructions save time during setup and reduce installation errors.
- Applications: While designed for pictures and artwork, these protectors also suit framed prints, canvases, and other delicate edging.
- Storage considerations: If you have limited space, prioritize compact designs or packs with fold-flat packaging for efficient storage.
When selecting a set, balance the number of frames you typically protect with how adjustable the corners are. For galleries, offices, and moving households, a mix of larger packs and flexible sizing often provides the best long-term value and protection.
