Custom Corner Protection for Every Industry

Carlisle Plastics specializes in custom-molded edge and corner protectors designed to meet the unique demands of a wide range of industries, from furniture manufacturing and glass production to automotive parts, construction materials, and electronics shipping. We understand no two packaging challenges are alike—sharp corners, irregular shapes, or heavy loads all require tailored solutions.

Plastic Corner Protectors / Corner Caps

Flexible, Lightweight, and Durable

Manufactured from high-quality PVC plastisol using our dip molding process, these protectors deliver a clean finish and dependable flexibility. Ideal for:

  • Covering sharp or hazardous edges
  • Preventing scratches, dents, and chipping
  • Adding a finished look to products
  • Shipping, storage, and vibration absorption

Common applications include furniture corner guards, glass corner covers, and packaging edges. With custom sizing and thickness options, we ensure the right fit—whether you need soft consumer-product guards or semi-rigid shipping protection.

Heavy-Duty Plastic Protectors for Metal and Industrial Use

Strength and Structural Integrity

Our semi-rigid plastic corner protectors provide rugged, impact-resistant barriers for industrial and commercial settings. They help resist compression and abrasion in applications such as:

  • Steel and aluminum part packaging
  • Machinery shipping
  • Pallet edge reinforcement
  • Structural component protection

Rubber-Like Corner Protectors

Shock Absorption and Non-Marring Contact

  • Glass sheets and mirrors
  • Acrylic and plastic components
  • Finished wood furniture
  • Electronics and appliances

These guards reduce cracking, breaking, or marring during storage or shipment while ensuring gentle handling when stacking or shelving.

Glass Corner Protectors

Precision-Fit for Fragile Edges

Designed to protect edges of tempered glass, mirrors, and sheet materials, our custom plastisol corner caps act as guards to help prevent cracks and chips caused by handling or vibration. Applications include:

  • Framed/unframed panels
  • Shelving units
  • Tabletop edges
