1. Why Corner Protectors Matter
1.1 Defense Against Physical Damage
Corners take the brunt of impacts during loading, unloading, or movement. Even minor bumps at vulnerable angles can damage frame integrity, particularly with delicate wood or ornate molding. Using corner protectors mitigates damage risk significantly.
Industry professionals note the importance:
“Corner protectors can protect framed artwork from nicks and scratches during moving or while in storage.”
1.2 Cost-Efficiency
Repairing or replacing damaged frames quickly becomes expensive. Corner protectors—crafted from cardboard, foam, or archival board—offer economical, reusable protection. They prevent dents without requiring full crate replacement.
1.3 Ease of Use
These are simple, fast, and usually non-invasive. Many options slide onto corners without tape, staples, or adhesives. When properly fitted, they stay secure until removed.
1.4 Stacking and Storage Protection
When framed works are stacked, unprotected corners can abrade against other frames or rigid surfaces. Protectors act as buffers, ensuring frames can be stored close together without damage.
2. Types of Corner Protectors
2.1 Corrugated Cardboard Protectors
The most common type includes heavy-duty 200# white cardboard versions. Adjustable and easy to fit, many can handle multiple frame thicknesses.s
- Pros: Sturdy, biodegradable, budget-friendly.
- Cons: May scratch delicate finishes if edges aren’t cushioned.
- Best For: Standard wood or metal frames under moderate handling.
2.2 Foam & Bubble-Wrap Protectors
Soft foam or bubble protectors offer cushioning and include versions that are L-shaped to fit snugly.
Reddit users report:
“Bubble corners are what I use… we buy bubble wrap in rolls and run a length down each rail.”
- Pros: Excellent shock absorption; kind to delicate finishes.
- Cons: Slightly more expensive; may require adhesives or inflation of wrap.
- Best For: High-value, fragile, or ornate frames.
2.3 Archival Board Protectors
Made of acid-free, buffered board, safe for long-term contact with frame finishes. Ideal for museum-level preservation.
- Pros: Archival safe, sturdy, reusable, protects fine finishes.
- Cons: Typically more expensive and less widely available.
- Best For: Museum collections, fine art storage, conservation-sensitive pieces.
2.4 Recyclable Paper/Cardboard Protectors
Budget-friendly, often mixed-pack adjustable types are sold in bulk. Easy to fold but may offer less lateral protection.
- Pros: Cheap, adjustable, environmentally friendly.
- Cons: Less durable, needs to fit snugly for effectiveness.
- Best For: Lower-cost or mass-framed works.
2.5 DIY Cardboard Protectors
Creative and customizable—watch YouTube tutorials on making your own (e.g., from recycled corrugated board).
- Pros: Custom sizing, eco-friendly.
- Cons: Requires DIY effort; variable protection depending on build quality.
- Best For: Workshops with budget or eco priorities.
3. How to Choose the Right Protector
3.1 Frame Material
- Wood frames: Corrugated protectors are typically sufficient, but foam or archival board adds gentleness for valuable pieces.
- Metal/Aluminum: Foam or archival board preferred to avoid scratches.
- Delicate finishes: Opt for protected inner surfaces (archival board) to safeguard patinas or gold leaf.
3.2 Frame Thickness
Ensure the protector fits securely. Many adjustable types cover ¾″ to 2″ thickness. Specify exact frame depth when ordering.
3.3 Intended Use: Single Trip vs. Long-Term
- Single shipment: Reusable cardboard or bubble protectors suffice.
- International shipping / multiple moves: Consider archival, rigid, reusable systems like acid-free board.
3.4 Budget vs. Value
Balance the cost with the protection level. For high-end art, spending more on archival board is cost-effective compared to damage risk. For general metals/prints, cardboard is economical.
3.5 Fit & Stability
Look for self-locking or gripping designs that stay on without tape/staples. Avoid an overly tight fit that could bend frame corners.
4. Best Practices with Corner Protectors
- Clean corners: Wipe briefly to avoid trapping grit.
- Install gently but snugly. Adjustable models allow depth settings.
- Secure as needed: Use minimal tape or stretch wrap for extra hold, especially on bubble types.
- Match to crate: Choose the protector type that aligns with the crate design and padding.
- Label orientation: Mark “This Side Up” or fragility warnings near protected corners.
- Remove after delivery: Encourage recipients to discard staples or tape upon unpacking.

6. Common FAQs
Q1: Are corner protectors necessary if using a professional crate?
Yes. Even padded crates can shift under impact. Corner guards provide targeted shock absorption and protect from abrasion.
Q2: Do corner protectors scratch the finish?
Not if chosen correctly. Foam and archival board types have cushioned surfaces. Cardboard protectors should fit well and be reusable, with rechecking before reuse.
Q3: Can I reuse corner protectors?
Absolutely. Quality cardboard, foam, and board types often feature reusable designs—just inspect for wear before reuse.
Q4: How many protectors per frame?
Use four—one for each external corner. Some opt for extra along the edges in high-risk transport.
Q5: Cost of adding protectors via the Union?
Costs depend on material and crate specs; start from modest fees for cardboard protectors. Contact Union FAS with frame dimensions for an exact quote.
