Corner Protectors & Edge Guards for Shipping

Corners and edges are the first points of contact during drops and rough handling — and the most common sites of shipping damage on furniture, frames, large electronics, and art. Corner protectors are cheap insurance against the most predictable damage vector.

Types of Corner Protectors & Edge Guards

Foam corner protectors

Pre-formed polyethylene foam corners that snap onto box corners.

Best for: Framed art, mirrors, glass panels, flat-pack furniture corners

Cardboard corner guards

L-shaped or U-shaped corrugated guards that reinforce box edges.

Best for: Large box edges, furniture shipments, pallet loads where cardboard edge crushing is a risk

Plastic corner caps

Rigid plastic corner pieces for heavy, high-value items.

Best for: Exhibition equipment, heavy electronics, high-end furniture

Foam edge protectors (rolls)

Foam in U or C channel that slides onto edges and corners — cut to length.

Best for: Long edges on panels, glass, countertops, and oversized flat items

Practical Tips

•Use corner protectors whenever shipping artwork with frames — unprotected frame corners are the #1 art shipping damage point
•Cardboard edge guards add meaningful stack strength to boxes — useful when boxes will be stacked in warehouse or truck
•Foam corner protectors are reusable — customers often save and return them for future use
•For palletized shipments, cardboard corner guards on pallet corners plus stretch wrap keep the pallet from collapsing
•Match corner protector size to the box thickness — undersized protectors slip off under impact

Frequently asked questions

Do I need corner protectors inside or outside the box?

Inside the box between the item and box wall for fragile items. Outside the box (on the box corners) for stacking strength and additional drop protection during carrier handling.

What size corner protectors should I use?

Measure the edge thickness of what you're protecting. Foam corner protectors come in leg lengths typically from 2 to 6 inches — choose long enough legs to secure firmly without slipping.

Can I use corner protectors on mirrors?

Yes — foam corner protectors on all four corners of a mirror inside a correctly sized box, with foam or bubble wrap lining between the mirror surface and box walls. Mirrors should always ship in mirror boxes (flat, shallow) or double-boxed.
